This is the closest grocery store to the Red Rock park entrance. We met several climbers buying their victuals there. As well as guides meeting their clients. One guide we met was called Rainbow. I think that name must appeal to the ladies. (In fact, a young woman in an expensive Mercedes sports car picked him up for a day of climbing.) If I hired a guide named Rainbow, I would run far away.
This is a photo of us buying snacks for the day. The good news is you could also gamble in the grocery store. What you eat in Vegas baby, stays in Vegas.
