I had no issues with it last season, and will continue doing so starting this weekend..Can you still bring a sealed bottle of water into the stadium? I didn't see it mentioned in the rules.
no problems with water bottles at the game ever. and given that they had about 25 heat related incidents last year at the first game, including 3 people that were brought to the hospital for hydration, I'd suggest bringing more than one or 2 bottles in.
