I'm planning a short, easy drive across the US next summer. I have a mate who lives somewhere on the East coast so I thought it would be better to start there and spend 3 weeks getting to know our distant cousins across the pond. I'm one of those people that thrives on random acts of spontaneity and I'd like my trip to reflect that, though obviously there needs to be some kind of structure to the trip.
Just wondering if there is anyone out there who has done the same thing recently, how it went, which routes or sights you recommend and what they spent for the entire trip? How easy is it to just arrive at a town and get a room for the night? As much info as possible would be welcome.
