There are a few sites that cater to would-be-hitchhiker types, where you can post your itinerary for a road trip and other people who are going that way can offer to ride with you and pay for gas, or vice versa... post looking for rides for longish trips. I forgot what they were called. Do you know of any? The problem is some of the sites are very general and have a lot of different types of people looking for and offering rides, and some of the sites are specific to this kind of "hitching culture", with mostly young hippie/anarchist/whatever type people. I am hoping to find one or more of the latter.
