I went to the 06 and 08 games as well.
The stadium was a morgue in 2006, and even more so in 2008 since they actually added 5k seats by enclosing the north endzone...go figure.
You can park within a 5 minute walk to the stadium for $10, and I scalped two tix for $20 a piece (06 and 08) and probably overpaid. Both games, I sat amongst the Iowa fans, pressbox side (west side), about the 20 yard line (south endzone side of field), approximately 35 rows up. The east side of the stadium was empty by the middle of the third quarter each game.
I'll add...if you haven't been there, Bloomington is situated in beautiful Brown county and is worth a look around. However, it's a hike to get there. I stayed overnight in Indy both times. They also allow you to leave the stadium and come back in with your original ticket.
