The math doesn't make sense. Parking was $5.00 for one car, right? If they charged an extra $5.00 per ticket, you would in effect be paying $10.00 for parking for the evening. Let's say you were a family of 4, that would be $20.00 you'd be paying.

And it really wouldn't be fair, as others have pointed out, for those who don't drive to the game and park at all.
