They initially had the lots closed and when traffic got backed up to where it was impeding the surrounding area the lots magically opened....was in the orange lot for that game and IIRC we were in around noonish maybe 1300.....in orange lot again for eers and plan on getting in line around noon with the hopes of similar outcome.
Make sure whatever lot you are in that you enter via the correct exits/direction, they will not let you cut through lots to get around the stadium, if that makes sense.
