The Wagon Train — Rene Goscinny

A wagon train of pioneers drives through Nothing Gulch en route to California. Its ill-tempered driver is sent away by the passengers, and Lucky Luke is asked to step in and replace him. He accepts, amused by this fun group. When the wagon train gets underway again, the trouble begins: A mystery vandal keeps trying to sabotage the expedition. But it takes a lot more than that to make Lucky Luke turn back!
