Have had a pair of seats for 3 or 4 years now. Figured might as well get them since we were going to a handful of games each season and paying above face value.
We go to 3 games a year, since it's a 9-10 hour drive from VA. The remaining games we put up for sale as early as possible. Typically, the only game that doesn't sell is one of the preseason games. A great feature is you can also donate the tickets to United Way of Indiana. Someone gets to go to the game who otherwise wouldn't (I guess), and it's also a tax write off. So if by Friday the tickets haven't sold you simply go into your account, pull them from the "sell" category and click on "donate."
I'm not aware of any away game perks for STH.
