There are only so many lots within a few blocks of this venue. Most are owned by the single company. Parking price is not known ahead of time. The full price (including parking) of attending the event isn't know until you arrive, after a long drive into the city. Sure $5 is fine, but it's demand-based. There's nothing that prevents them from making the price floor $50 for a large name artist, and attendees would be caught in a lurch. The whole operation rubs me the wrong way.
