Ridester is a service that allows you to find a ride from one city to another, anywhere across America. You sign up as either a driver or a passenger and they take care of hooking them up with each other. You get to enter information about age, sex, music and smoking preferences, along with other information so that you can find a driver or passenger that you can manage to sit in a car with for long hours without going crazy. There is also a community feedback system so that you can find out what other folks have thought about this traveling companion in the past. It's a free service and well worth a trip if you are in need of a lift or looking for someone to split gas money with.
