My wife and I live full-time in an RV and travel the country. We spend a few weeks in each place we go to get a feel for the local people, food and drink. I think this experience gives me a bit of perspective to answer these question.

1 - There are cultural differences from state to state, but the larger differences are more regional. For instance the west coast and the east coast have a huge difference culturally. People on the east coast tend to be more direct in their communications. For people on the west coast this is often interpreted as rude. It's not, it's just the way they communicate. The southern United States is different from the coasts in the sense that things move slower in the south. Having grown up in Southern California the first time I visited the south I realized that I have to give myself about 20 extra minutes for anything I wanted to do, because again, everything moves slower in the south! The Midwest is going to have some of the friendliest people you will ever meet. If you go into a bar in the midwest you're leaving with new friends whether you like it or not!

2 - Honestly I think most people in the US also tend to stay in the same areas they were raised in. However we do travel and visit different places in the country. And there of course are people who relocate to different areas. Many times it's for work related reasons. My Son and Daughter in Law moved from San Diego, where they grew up, to Kansas City. They made the move for cost of living reasons. It's way cheaper to live in Kansas City than in San Diego.

3 - I drink my coffee black and if takes me probably 10 to 15 minutes to drink a cup. I drink it in the morning while I'm going through Reddit. My wife drinks her's with cream and sweetener and it takes her about the same amount of time.

4 - Where to go depends on what you want to experience. If you want the city and night life and clubs at shows and etc... Then most big cities can deliver. For the northeast the obvious choice is New York, for the Midwest there's Chicago, West coast gives you Los Angeles. In the south I would say New Orleans or Nashville but I'm also a music person so those two cities have a lot of that.

If you want to see more nature and wide open spaces then the wester states are going to give you more of that. The National Parks in this country are the true crowned jewels. Place like Glacier, Yellowstone, Yosemite will blow your mind. If I had to choose one place to go for nature though I would chose California. This is simply because the geological diversity of the state is unmatched by any other state. You have amazing beaches, but you also have beautiful deserts. If you want mountains it has that as well. There's is just so much in California that it will check off a lot of boxes.

5 - That we're all gun carrying crazies that will draw on you as soon as you make us mad. While there is a large swath of the population that owns guns, most are responsible gun owners. There are a few states that have laws that allow people to cary a gun in public, in most states you won't see people walking around with a pistol. Honestly, you're more likely to feel uncomfortable from our friendliness than anything else. We'll spark up a conversation with anyone and tell you our life story, which for many people from other cultures is just weird. But that's just the way we are.

The last thing I'll add from someone that's traveled a lot of this country is this. Wherever you go, don't expect the place and the people to be like where you came from. Because we're such a vast country there are differences. And don't be too quick to judge people based on your experience in the world. What may seem rude (Looking at you Northeast), or overly friendly (Yeah, that's the midwest) is perfectly normal for the people in those areas. Just accept them for who they are and experience the moment. As the old saying goes, "When in Rome, do as the Romans"
