The ACC is a bit different - I have no idea where you'd "stand and listen" anyway, except maybe inside Union Station. Not to mention, the band's entrance is underground so they do not walk out of their cars at any point in any area which the fans would have access to. Today they probably would have parked outside based on nobody being there, but when arriving for sound check the day of the shows, you will simply not meet them at this venue. The way it's set up is they turn into the underground parking right before the road that takes you to the onramp of the major expressway, so it's not like they'd stop the car there and walk out to sign autographs.
