There Goes a Bus is an information-jammed journey into the secret lives of the thundering buses that thrill us when we're little. The beloved yellow and black ones are only the beginning: besides city buses, cross-country Greyhound types, and touristy double-deckers, we also get a lift on an articulated number (the kind that bends) and--the traffic stopper--a bus that, when driven into water, becomes a boat. Stops for maintenance and under-the-hood investigations keep the wheels going round and round, and rap sessions with a bus-driving honcho buckle us in for the long haul.
