I was wondering if anybody had any advice on a trip of mine that I am planning. Me and my two best friends are planning a trip from Boston to California. We are all 19, but very mature for our age. We have been planning this for a long time. Anyways, we are thinking we are going to drive down through Virginia, then go west through St. Louis, and south from there towards Vegas. After Vegas we were going to drive up the CA coast and then head back east. We already got a National Parks pass and have all the maps, etc. My friend is bringing his GPS unit also. We have set aside 3 weeks for this adventure. Do you guys think that is enough? Too much? We are planning to camp and use hotels. Obviously we want to view all the big things along the way, and some wacky spots also. We are planning to leave on June 15, in my ford escape. Any help or suggestions would be awesome. Thanks!
