Not sure if I should post here or not, since my thought is that the OP was thinking more in terms of those not from the states and where they'd like to visit.

But if time and money were of no object and I could lead a tour of the US, I think I'd like to show you:

Washington D.C.: Not for any particular political reason, but so you could see some amazing museums and the historical sights that so recently were the places from which those with a dream helped stitch together a nation.

Our former 'rustbelt' cities: Chicago, Cleveland, Detroit. So you can see that we still keep reinventing ourselves from cities that were the backbone of manufacturing and now are becoming more cosmopolitan, but still with a bit of broad-shouldered, plain-speaking honesty to them.

Appalacia: The entire spine of theses mountatins to the Smokeys. What amazing vistas. What peaceful streams. The dawn breaking over a ridgeline with the scent of pine is something that will stay with you.

New Orleans: To show you that despite hardships, we still love our food, drink and merryment.

Texas Panhandle: You need to stand out on a scrub field and see nothing in every direction. It makes one truly humble.

The Rockies and Bad Lands: Haunting and comforting. The scale of these sights are again humbling.

San Francisco: A great walkable city with some of the best food anywhere.

And for my own homeland...I'd show you the deep forests and cool running trout streams of northern Michigan. Sitting on a rock watching otter take your trout. A red-tailed hawk circling above. Deer in the woods behind you. Pulling walleye into the boat as we fish our great lakes.

We'd stay until the first snow so you could hear how quiet but still how alive the woods are.

From history and culture, to natural beauty, to hussle and bussle and back to simple things like hay cutting in August and dinner with friends.

That's a tour I'd like to plan for you.
