The shelter is located about 200' below the ridge. In the late afternoon, Wade was up on the ridge and he found a big rock that he wanted to roll down the hill (what is it about scout age boys and their penchant for rolling rocks down hills??). I yelled, "Wade, Don't you dare do it!!!". The guys all yelled back, "Wade, Do it! Do It". Well, Wade listened to his inner boy scout and rolled the rock down the hill. Fortunately it missed the shelter.
