Ok - I've got to Nashville now - but facing a small problem - accomadation (for under $50) ! The only option is looking to be a bus in and out of town for 4-5 miles to get to a "Motel 6" - which is my entire daily budget just on accomadation. Given I can then spend the next day on a Greyhound bus (free accomdation) I guess this balances out - but it still kinda sucks.

Europe was littered with Hostels I seem to recall - is the US just not so hot for Hostelling ? Answers / useful URLs for finding non-HI hostels on an e-mail :)
