Traveling for a month in the United States. Where can I go?

I finished college in early May and want to travel to the end of June I'm starting Grad School June 25 I will start in Maine, the drive across the country to Seattle and then Los Angeles and Virginia for school. My Roadtrip probably me gas cost a lot, but I want a big adventure before returning to school for 3 years. ANYWAY, where can I stop that? What are some of their favorite attractions, summer festivals, cities, national parks, etc. I will definitely stay on a budget (camping, sleeping in the car, crashing on the couch or in shelters). Hopefully I will bring my sister with me to share gas costs. Suggestions on things you should not miss? Thanks Thomas. "Back home "will be part of the trip. My brother lives in LA My mother lives in Orlando and my father lives in Virginia (my last stop) …

If you want a real adventure, why not go to Europe? For Paris, Amsterdam or Prague. It will not cost more than driving across the United States.
