Just a note, I went to today's day game (12:35 PDT) at Angel Stadium in Anaheim with my 7D and 70-200 f/2.8L IS II. Security said the lens was "too big" and cited the 4" rule. I wasn't going to argue the point since I figured I'd try my luck to get it in and was well aware of the policy before hand.
I've been into Angel Stadium before with a 70-200 f/4L and 200 f/2.8L II on various occasions with no issues. Not sure if the 70-200 f/2.8L IS II is too beefy looking and attracts too much scrutiny.
I'm just posting this as a "Your Mileage May Vary" note for anyone thinking about bringing a long lens to Angel Stadium.
