Do I need to purchase parking for my conversion van prior to the game and how

Yes. It's best to pay for advanced parking. Day if events they are full. If you don't mind walking. You can get further away.

Michael Vincent if your going to a.game check on ticketmaster. We went to the Garth Brooks concert and we uberes it

I honestly don't know. We parked in a parking garage because the road near the Stadium was closed
