Im going back to my statement. After game time is one thing, at the park you are there for the kids, i have used this time for vacation as well, but at the park is just wrong. My girls would not mind if I had one but I am there for them not me, so have some at dinner, hotel kick back and relax. NOT ON THE FIELD parent or coaches, if you cant there may be a bigger problem. It will dehydrate you, and what are you teaching the kids, you cant spend a day at the park just drinking water, pop, gatoraide.
