Riding Greyhound is a very cheap method of travel if you absolutely can't spare the dollars, but it is excruciatingly slow. Do not expect to arrive at your destination close to when you'd get there driving yourself. The times I have traveled Greyhound the route was slow, the driver didn't follow interstates but used US Highways and stopped in almost every BFE town known (or not known) to man. I rode once from Birmingham to Mobile Alabama and what would have been a 4 hour trip by car was a 10 hour ride by bus. Bring some Nethack with you, you'll need it.
