I am strongly in favor of this and have been for several years and I have a family with an 8 year old. I was driving today and they were quoting someone from Maryland on how this could actually HELP drinking related problems. They said the typical fan ( who drinks ) binge drinks right before they enter the stadium. They either do a bunch of shots or chug beers. Now with beer and wine being served, they feel it will cut down on binging and encourage a more responsible rate of consumption. I don't really have a strong opinion but they might have a point if we are all being honest here.
They say if it makes dollars, it makes sense. I personally go to a local bar or restaraunt with family for half the games to "tailgate" . If we had beverages my money would start to shift more to the game. If I pack a case of beer to tailgate for real, I likely would pack less and have more at the game instead.
It is certainly a revenue stream and it would certainly make things louder. Those are facts. Security is hired so let them do their job if things happen to go wrong. I go to games to have fun and this adds to it for many people.
You don't need to drink to have fun but a football game day in my opinion should resemble a cocktail party and less like going to a kid's birthday party.
