The shuttles are somewhat dependent at game end on how the crowds trickle out on getting picked back up. So if you can pick a parking lot that you can walk back to you'll be happier. I used to park at the closed used car lots and the walk wasn't bad when I was in my 20s for Ranger games at the otrigjnsl Arlington Stadium, but I'm of a certain age now that whole that nice of a walk should be wonderfully invigorating now, I tend to avoid them on game days. That part of Arlington varies on its seediness now, too…
The primary lots will be a little slow to drain, too, and sometimes they block streets to manage flow. That was why I parked in the local boondocks.
