The problem with putting down the money for me is, if I don't get season tickets this year, I'm not sure I'll want them next year. I just moved to Rochester and only know for sure I'll be here till May 2017-ish finishing my dissertation. After that, it is open book. So if I don't like the tickets I get stuck with this year, I may not get anything and will eat the money.
Doing the rough math, based on years of ticket buying from eBay/stubhub/scalpers/getting free ones from friends who don't want to go at the end of the season when it is freezing and they suck, it may make more sense to go to every game and not have season tickets and just buy for each game.
