Me and three of my roommates are planning a cross-country roadtrip after graduation from college this coming May. We are from Southwestern Virginia, and are interested in traveling west. We really want to see some of the National Parks (definitely Yosimite, Yellowstone, and Grand Canyon) along the way and would like to end up in California at the end of out western journey. We will only be able to spend a maximum of about 14 days for the trip (there and back), and are looking to do it as cheap as possible. We aren't too concerned with seeing a lot of the big cities along the way. I was wondering if anyone has made this type of trip before, and if so how much are we looking at spending, and are our goals realistic (time wise). I have already looked into the National Park Annual Pass, and think that would be the best bet. Also, we plan to camp in a tent at low rate/free campsites. Any info. would be great.
