As for my thoughts on prices, it's the playoffs. They charged what they thought the market would bear. Seeing as the lots were jammed up both games they must have set the right price point, and are probably thinking they could have gone a bit higher. I haven't crunched through the legalese and I am not sure exactly how the lots are titled, but I'll chip in my best legal guess. I believe the lots are held in a trust that the Stadium District runs, like allowing them to contract with MPD or MCSD for extra security on premises. The parking pass give you a license to be on the grounds, subject to the posted rules. The rules are observed more with large crowds, too much liability. 2.5 hours after the game somebody cracks their head or gets in a brawl they don't want the tort lawyers sniffing around. Besides, you really want to hang outside and drink, well, you don't have to go home but you can't stay here. Think of the 1 hour rule like paying a quarter for a cart at Aldi. they are keeping the costs low.
