First some clarification. From what I've seen "happy Christmas" is more popular over there, but we use "merry Christmas". There's also a difference in the word holiday. Few people here would say, "I'm going on holiday to Aruba." We would say, "I'm going on vacation to Aruba." However, we do say Christmas, Easter, and Halloween are all holidays. Do you also use holiday as a noun like that?
Most people here refer to the winter holiday as Christmas. About 70%-80% of Americans are Christian of one kind or another, so they pretty much have free reign. Some companies are trying to be more open to other winder holidays and are instead using the euphemism, "happy holidays." That way they don't alienate those who celebrate Yule, Hanukkah, Dies Natalis Solis Invicti, and other December holidays, but that has created a lot of black lash from the conservatives who claim that those companies are trying secularize their religious holiday. Of course, considering that Christmas has been, by far, the most commercially lucrative holiday for decades I don't think that's the case.
As for myself, being secular and iconoclastic I make it a point not to celebrate any holiday during this time of year. Come Christmas Day I slept in, played videogames, and ate dinner alone at a Chinese restaurant since it was the only place around that was open on Christmas. God bless those Taoists.

I still saw my family the week before and after Christmas since everyone had the time off and we could get together. I also feasted nicely and had a good time, but for me there was no religious undertones or even secular traditions to be observed.
Thank you very much for the elder flower cordial recipe. I'll keep a copy of it, but it'll be awhile before any plants will be growing again.
As far as the democratic candidates are concerned it looks like it's going to be between Hilary Clinton and Barack Obama, so he does indeed have a fighting chance. I'd actually prefer him over Clinton personally, but after the long reign of Bush, I'd take any democrat I can get! Personally, the candidate's race or sex doesn't affect me at all, but I'd be lying if I said that they're not important here. We haven't had 43 rich white male presidents because we're equal opportunists.
That cottage does sound nice, regardless of its modernization.
My sobriety is partially due to growing up in a home where alcohol was abused quite regularly, partially from not liking the taste of alcohol, but probably mostly from not wanting to alter my state of mind. I have no fear of a vengeful god who would get upset at my drinking, but more fear of waking up in a ditch with five dead hookers, a crashed car, and no clothes.
I think one of the problems with American culture is how we demonize alcohol and prohibit it's consumption to anyone and everyone under the age of 21. I'm usually against age restrictions of all kinds, because by the time a person is 21 they don't magically gain the responsibility to handle alcohol. Most of the people I know who are the most responsible with liquor are the people who have been drinking it since they were 12 and understand its risks.
You're right of course, dressing like a rogue and not accepting a belt of liquor is kind of detrimental to my persona. But, I can always use cider or tea and claim that it's alcohol.

While I haven't experienced the romantic connection that people have with certain types of alcohol, I do understand what you mean.
Actually, even individual counties can make their own liquor laws. Some of the university towns will prohibit the sale of alcohol in grocery stores after midnight, but most of Michigan is pretty lax about it and you can buy single containers of most drinks. Some states are really controlling though. The state of Utah doesn't even allow the full legal limit of alcohol in their beer because of the large Mormon influence. There are also some odd federal laws. For example, when you purchase alcohol the store clerk is legally bound to put the bottle in an opaque bag before you leave the store. It's also illegal to put alcohol in a container different from the one you bought it in. Crazy!
I am quite fully assimilated into the American culture, despite my attempts not to be. I'm the kind of person who understands that the words "culture" and "cult" come from the same prefix. My ancestry can be traced to Germany, Italy, and a couple other places I'm not sure of, but as for my culture, I'm fully American.
As far as guns are concerned, there are at least three stores within ten minutes driving distance from me where I would only need to pay about $200 (around £100) and have a shotgun and plenty of ammo. No waiting period, no background check, no hunter's permit, nothing. All I would need is a driver's license that looks valid. Some weapons, like hand guns, require a background check, but for some reason shotguns don't. Personally, I think that's a problem. Although I don't own any guns I'm certainly not against them, in fact I kind of like them. However, I just think that background checks and safety courses should be mandatory for owning something that can very easily kill another person. They have very -very- slowly been passing bills to prevent people from getting military grade assault rifles and guns that can fire more than X amount of bullets without reloading, but we still have several thousand deaths from firearms every year.
Shingles are basically large fiberglass asphalt panels that are overlapped and nailed to a roof as a low cost facsimile of tiles. The Wikipeida entry on "roof shingle" can give you all the details. From what I've heard from older people, that just like vinyl siding, shingles used to considered ugly and few used them, but their low cost and effectiveness allowed them to become more popular, and now almost all houses use them. It's normal to put new shingles over a layer of old ones because removing an old layer is very messy and expensive, but most professional companies will always remove the old layer first. I've heard that aluminum roofs are starting to become popular because they last much longer and can be made nearly noise-proof, but I have yet to see any around here.
Housing has taken a bad turn here in the States, which I'm sure you've heard about. The failed sub-prime mortgage market seems to be causing the stock markets all over the world to take a dive. Even still, we have something here called the "American Dream" which is basically just a repackaging of "Manifest Destiny" if you ask me. The American Dream states that any man who works hard is owed his own house, car, wife, kids, dog, and white picket fence. What it really means is that anyone who gets a bunch of debt from loans to buy houses will be in debt for most of their life. I have a nice sized apartment and the maintenance group fixes everything that breaks. I may have noisy neighbors, but my rent is about half the cost of a house of equal size.
I usually don't go that far away on my vacations. Usually, when I have time off of work, I stay in the area and just do things that I can't normally do like go to amusement parks, ski trips, or something like that. Occasionally I'll go a decent distance away. Last summer I went to the state of Tennessee, the year before that I went to the state of Washington. Those locations may seem awfully similar since they're in the same country, but with such a large country the cultures are actually wildly different. The food, the lifestyles, the taboos, even the language is different. While most of the US speaks English, a lot of places near Mexico and the Caribbean have a high Spanish speaking population. Also, the accents and idioms vary dramatically. While I've never been there, I assume that it could be likened to the differences between the UK's Great Britain, Wales, Ireland, and Scotland.
