Thanks Dave for inventing this game. It has given my family a great family thing to do together. My kids are teenagers and they love to go caching. How many parents of teens can say they have an activity that their kids enjoy doing with the old farts? Fromwhat I see today not many I would guess. My wife and I just had our anniversary and we cached to, from and at our getway place. It was great fun. We cache both on foot, by bike and by car so for those that are green inclined it is not all bad. Thanks again and cache on!!! Bill the Cat
