While in Arizona, Harry parks the motor home at the Grand Canyon by the Colorado River. After camping outdoors, Lucy falls asleep beside the river's bank when her mattress starts to get carried away with the current.
Kim, Craig, and Harry try to rescue her and take a speeding trip down the wild rapids to catch up with Lucy on the float-away bed!
Special Notes: This is the final segment of the four-part opening for the season. Lucille wears a wet suit and does almost all her own stunts, spending hours in the freezing water. Director George Marshall has a cameo at the end of the episode. George directed Lucille and Bob Hope many years earlier in Fancy Pants.
