Been in Ski U Mah lot since the beginning. Lot is consistently half-full yet is "sold out" according to the ticket office. Parking staff ridiculously cordons off and reserves half the lot for late comers who do not show anyway. A better game day atmosphere could be cultivated if they adjust how they park fans and make the parking passes easier to transfer. I was told by the ticket office parking passes cannot be PDF'ed or otherwise emailed through StubHub, etc. I'm 50% sure the ticket agent did not know the accurate answer when I inquired if this was possible. I often find expertise in that office sadly lacking...
If you are a season ticket holder you should have just bought the pass when you renewed (for a mere $1150) as that is your only way to guarantee a tailgate spot. Otherwise, you might have to track down someone willing to sell their hard pass off of Craigslist. Good Luck!
