Looking for any help or advice on the planning of a road trip. I really haven't done anything like this before, and I figure what a great reason to go but because of my college graduation. A friend of mine and I have decided to try and drive cross country, starting in Philadelphia and just work our way west, but we are both unfamiliar to the world of long term road trips. So I guess I was wondering whats the starting point? There's the obvious places we'd like to see, Grand Canyon, Yellowstone, etc...but what i'm really looking for is the unusual. The small stuff to me is the big extraction, the things only people would know about who have taken the same trips and routes. So I guess my first question is routes? Any road suggestions, and even approimate costs? We are hoping to do it for about 16 days or so 18 at the longest. It's kind of a way to cap off our college careers and a way to start our new careers off the right way, so any help is greatly appreciated. Thanks........
