Travel High on the Hog -- Ride the Bus?

Peter Greenberg recommends taking the bus for trips under 500 miles. On top of beating planes and trains for cheap ticket prices, many have cell-phone reception, power outlets, wireless Internet access, videos, leather seats, and an on-board attendante with snacks and beverages. He mentions Megabus, Boltbus, Greyhound, Peter Pan. Online bus ticket brokers are BusJunction and GoToBus.
