Work through the VASF if you want tix every year. You have to make a donation to get points. If your points are high enough to qualify, you can purchase season tickets. I think the minimum for ticket consideration is $500, but to make sure you'll want to go higher. If you're not a letterman, you'll need a five figure donation to crack the lower deck.
If you don't want tickets in the same seats every year, I've seen you can buy a set of season tickets on ebay for about the same amount of the tickets and donation.
