We switched to the one gallon jugs last year. To me this or even the half gallon jug is the way to go. They leave the band hall with it filled up for either away or home games. We don't have to worry about filling them up again because drinking an entire gallon of water in the stands is probably not going to happen. We did this for contests, too. They had enough water to drink after the competition and for supper if we had to eat.
