On the Tennessee-Georgia border is an area called Lookout Mountain. It has a lot of interesting tourist-type activities for you to explore - if like those kind of activities. If you are into US Civil War history, there are a few battlefields in that area, too.
That would be a hard generalization to make. Some Americans are friendly and would be gracious in welcoming a visitor from another country. Others might not be so willing to be bothered. If that happens, don't take offense or assume that's the way everyone is. Simply be friendly and outgoing yourself and you'll meet all kinds of people and have a very pleasant time.
Well it's a pretty big country, can you be a little more specific? I'm a flight attendant and I fly all around the country, from my experience I can tell you that people on the southern states are the friendliest.
The states you mentioned in your comments are friendly states. Everyone will be friendly if you are friendly to them except a few like those who answered here. I am so embarrassed that your question is being met with such rudeness here. Not all of Americans are this way. Come and enjoy your visit and have some places planned out to go visit. People will be kind wherever you go if you are also kind to them. Have a good time here!
We're pretty open people, here, so there should be no shortage of people to talk to. As for great places to meet some of us, as long as you can see a house, chance are someone's home. Cities like Boston and Philadelphia are good choices.
