The America I lived in was full of people from many places around the world, or their relatives were from many places. A huge country with every climate from the tropical in south FL to the desert in the southwest. Mountains, oceans, prairies. As an American you have the opportunity to find your niche, your fit in a community. Ski community that is very liberal, or a beach community that is very international, or a rural community that is very conservative, and everything in between. I agree with @wundayatta that we are made up of many local communities and easily can be unaware of the rest of the country out there. In fact in the American south I feel a distinct lack of connection with the former countries people’s families are from, and an absence of second languages being spoken.
My earliest memories are living in NY, the suburbs of NYC, my school, playing with my friends, going to the local playground in the summer and getting ice cream from the Good Humor truck. They also had events throughout the year there like easter egg hunts there. Nearby we had a pond we would ice skate on in the winter, and go sledding down the small hills where we lived. Halloween, Thanksgiving, Christmas, Memorial Day weekend, all these holidays that everyone’s celebrating in their own way across the country. Memorial Day weekend when I was little was the day the pools opened, kick off to the summer. I don’t celebrate Christmas, but basically the whole country does, and I like the parades and the nutcracker and all tose traditions we have. It was overall carefree and happy. I think this is fairly typical Americana, with some difference depending on climate.
As an adult, one thing I really like about America is overall feeling comfortable anywhere I go in America, even if it is very different from what I am accustomed to. Like @yarnlady pointed out I can travel for 3,000 miles and there will always be someone who speaks English. Overall people are helpful. And, although I feel the country is too full of chain stores and restaurants, sometimes, especially when travelling, I appreciate it. Appreciate being able to stop along the highway for dinner and knowing what type of meal I will get at a particular establishment.
In my opinion America has become more and more divided politically and it will harm us in the end.
Americans tend to love new things. New ideas. New gadgets.
We are getting bigger and bigger, too much crappy caloric food. Fewer and fewer people cooking from scratch.
We are busy, overwhelmed all too often.
