Andy heads to the hills for a little peace and quiet ("Andy's Vacation", Episode #118). There's only one problem: Barney and his able deputy Gomer have let their prisoner escape. He too heads for the hills, and is eventually drawn to Andy's good cooking.
It really won't matter that Andy recaptures the prisoner because Barney and Gomer will be along shortly to let him go again. The great outdoors was never this wild in National Geographic.
