Sorry - I'm not justifying not joining the day-of-release bunfight with the hope/expectation of getting a space later. Parking release dates have never been on my radar at all, and I've nearly always been able to pick one up on the week of the game, generally when someone posts on here that...
I don't think they will any time soon as demand exceeds supply by such a great margin.
All that would happen is the parking STs sell out within seconds of release leaving only a few spaces available match-by-match.
I don't think I've ever bought parking upon release as I've never known when parking is released.
But if it does really sell out in seconds, it does seem the extra spaces released the week of the game are easier to nab - that's where all mine have come from, and there are still Wolves spaces...
