It began very simple: Derpy wanted to take Dinky camping, but soon the Cutie Mark Crusaders joined the trip. No problem. But, soon, Pinkie and Wilcox come along, and things get complicated. She realizes that she can't fit them all in her car, but doesn't want to dissapoint her daughter, so she rents a Buick Station Wagon from Fleetwood's lot, and sets off. Some wrong turns, and the group is stranded many miles away on a lonely highway near Apploosa. What will happen next?!
