Insisting that he can handle the responsibility, Wally (Tony Dow) asks to be allowed to escort Beaver (Jerry Mathers) on a 90-mile bus trip from Mayfield to Crystal Falls. Unfortunately, once they've arrived at the bus station, the boys get separated and Beaver gets on the wrong bus, one headed back to Mayfield. Meanwhile, Wally tries to catch up with his elusive brother -- by boarding the next bus to Crystal Falls! Future M*A*S*H and Bob Newhart Show scriptwriter Bill Idelson can be seen as the newsstand worker. ~ Hal Erickson, Rovi
