Also, does AT&T park allow a 70-200 into the stadium? I know some places can be a pain sometimes.
I know I'm day late to the conversation, but I go to AT&T Park all the time. I take the 70-200 and the 100-400. Like tagnal said you just can't block any ones view. If your sitting in the seats just watch your lens on hitting people in the back of the head. I know this is redundant information, but I hope it reassures you.
