I have noticed recently, while searching for UM season tickets on the secondary market, that people are selling their FREE spring game tickets for money! I have seen some as high as $30 a ticket for section 1 row 51. This guy in GR was selling some on craigslist for $25. I cannot even begin to describe my disgust for people that are doing this. If you don't plan on going to the game and have seats on the sideline why not give them away to someone that would actually use them and enjoy the experience.
