We will be in USA for 12 months , what are the absolutely must sees and dos. We enjoy national parks and history.
Wow a whole year should give you plenty of time to see America. Arches National Park is one of my favorites, as is the Grand Canyon. The west coast is filled with amazing national parks and scenery. History wise you may like Bandelier National Monument in New Mexico which features ancient houses from over 11,000 years ago. Roadtrippers.com is helpful when planning a long road trip like that. about 7 years ago
The average temperature is 71.8 degrees Fahrenheit but Nashville can get very, very, humid so it wouldn't be unusual for it to feel much much hotter. My best advice would be to pack for changing weather. over 7 years ago
Geppi's Entertainment Museum is pretty cool, lots of old arcade and pinball machines that you can play with. Link: https://roadtrippers.com/places/geppis-entertainment-museum-baltimore/51a08ce07f3d770a09005cf6 about 7 years ago
