Ha! True that. I do love to talk to people when I'm traveling but there have certainly been times in the lounge on Amtrak when I'm talking to someone and then realize they're a little crazy so I excuse myself to go get another beer, then sit someplace else when I come back. On a bus or plane there is nowhere else to go. It's one of the main reasons I don't strike up conversations on a plane.Surprised no one has added this comment: On Greyhound, you MAY also be at the mercy of some of the other passengers.Greyhound serves more cities and tends to have higher frequencies. Also, lower prices. Is at the mercy of traffic.
Amtrak is more comfortable, has better bathrooms, and food service. Is at the mercy of freight delays.
