All Wall Marts aren't the same. I went into one and it didn't have hardly any food in it. I shocked. We went to Yosemite and it was very dry. It's the end of the summer and the Yosemite falls were dried  up. So there really wasn't any water fall. It made me a little sad. It was also very, very, very crowded. Big hint when going to the park go in the spring when it first opens. It's not so crowded and it has water. Big hug to all. TTFN BJ
