When Aliens Camp

Dick takes the family camping as a mission bonding activity. At the campsite, the family and Mary all become angry with Dick -- the family because he lies about bringing Mary along after he tells them it's ""family only,"" and Mary because he tells her the family doesn't mind she's coming along. After they all cast him out, Dick goes off by himself and attempts to form a new society with a troop of Beaver Scouts he encounters. The Solomons assume Dick is lost and set out to find him. They (especially Sally, who resents her command being usurped) initially reject Mary's offers of help in finding Dick... until they realize she knows a lot more about the outdoors than they do.
