It probably will be a bad experience for them. I don't care if your kids are behaved or not your kids are going to see a bunch of drunk idiots. My daughter (13) and me had a guy behind us last year that called every play before it happened and he was wrong 90% of the time. "Oh shit let me guess here comes Weisman left. Hey what do you know we didn't run left, way to mix it up Ferentz you cock sucker." I bet we heard that line 50 times during the game. Now we just made fun of him the whole game and said "wrong again" every time. But at 4 and 6 your kids won't understand that the people around them are complete tools.
