Baseball, Hot Dogs, Apple Pie and Child Friendly Ballparks?

Yesterday I attended the LAST Shea Stadium Opening Day. Thank you to Rae, BH, Ed, Sean and Shimmy for making that happen.

I MUST bring my kids to Yankee Stadium this year.
However, after experiencing a wild upper deck at Shea.....Do I really want to expose my children to the inhabitants of Yankee Stadium? Anybody have any suggestions? Shall I dare check out the No-Alcohol Bleacher seats?

I really wanted to see my boys tonight. When I arrived home, they were already asleep. Trying hard to fix that daily weekday routine.
