He's mad because the ladies didn't pack the checker board.
Speaking about camping and beef. A few months ago My son Dan and his family were out camping along the coast near San Rafael Ca. They have a Corvair Ultravan, a rare camper powered by a Corvair engine. Where they were camped there are cows wandering around the area. Sometimes the cows get close and brush the camper giving it a bump. Well, that night, Dan was awakened by a bump, but the bump kept bumping and shaking. It turned out to be the large earthquake which did some damage in Napa. They didn't sleep very well that night!
