When will the parking lots open on Opening Day?

[National Defense]

agreed, when the line to enter the lots builds up they will open before the announced 4 hour advance time. if we all show up early, they will have to open the lots @ noon

I definitely want to get the party started around noon.

What gates? The lots may be open but I have waited at least 45 mins (at the 4hr mark) for exit 16 to Arena drive to be opened. By the time I get into the green lot, some tailgaters have burned their burgers already. I guess the secret is to know alternate routes into the stadium.
