We've only ever eaten at an In-N-Out Burgers twice on our visits to California. In fact, many years ago I spent a summer in southern California and never laid eyes on an In-N-Out. So, I'm not exactly sure in what regions they are located, but it's a chain with branches even in Arizona. The restaurant offered a map for people traveling by car this summer to locate restaurants along the way. It would have been fun to get one, but I am learning to be more concerned about the environment and not so wasteful.
