im guessing you have not attended games with children. my oldest is only 2 1/2 and it is the only real way to keep her in a seat for more than 1/2 inning! also, as has been said, we can bring in drinks for everyone for the price of buying one at the stadium. granted sometimes these are "special" drinks...which is probably another reason why they may stop allowing carry-in drinks. i will always bring in peanuts or sunflower seeds. i cant imagine those being taken away. if anything, allow separate entrances for people carrying in if their worry is getting people in the doors. that or realize that the days of getting from your car to your seat in 10 minutes is long gone.
