My friend and i are thinking about a road trip across the U.S. and we are just at the very beg. stages of thinking about it. i guess we just are wondering what the average time is for a trip like this, we don't want to be gone to to long but don't want just a drive though. And as we are both fresh out of college money is kinda of a restraint. is this a too big of a thing for us? and are there other sites which might help us plan things?
