Cheb is a city in Czech Republic.
There might be some good spots in or near Cheb to hitchhike, but the best thing to do (according to someone) is to take the train out of the city. There is a direct trainline to Prague (it will take 4 hours) for 400 krones. The city of Cheb is filled with prostitutes, and guys who are trying to take you into a Penzion. Don't enter! They will most likely scam you.
