I would look for places around national parks. The areas near the big parks are usually quite pristine and not developed. You could stay on site at a national park lodge. Yellowstone, Zion, Bryce Canyon, Rocky Mtn, Crater Lake, Arcadia, Yosemite, There s so many to choose from. Sorry it s not much info, but hopefully it gets you started.
Wyoming or colorado?I m from southern Wyoming/northern Colorado right on the border of both states.I would suggest going to northern Wyoming or Southern Colorado I know for a fact those are nice places to be, but don t go to where I am from it s really slummy there and a lot of gangs.
Key West, Florida!If not Key West, a few of the islands in the Keys!
try the mountains or some where tropical
