I've been to ten different MLB stadiuims, half have had huge signs, or at least people saying, "Don't go to your seat during an At Bat" or something similar. The Brewers choose not to educate the fans on baseball courtesies.... not sure why not. Moreover, the avg Brewer fan is a kind and courteous person. Yet, Most of these people have NO CLUE about when to stand up, move out, or move back to their seat. Then again, if baseball games are going to last 4 hours, I might give up my learned baseball courtesies, as well.
