I am a college student, and graduating this year I feel that there is alot of things that I wish I would have done and want to do something this year worth remembering. I want to plan a cross country trip, from pa to either california or washington and then back. I have about a 3 week time table to do this. Any idea what would be a good route, for entertainment and enjoyment purposes. And also how much would something like this cost(trying to get 4 total people on it), I'm gonna need a little luck convincing some of my friends to go with me, but I feel it would be well worth it. So what would be the best places to visit and what would be the best way to go there and back?
