I know the MGoBlog winds have shifted against football season tickets and the pyres are lit throughout Ann Arbor, but I have an update for those of us who have dared to renew and upgrade our season tickets.
The Michigan Ticket Office (phone number: (734) 764-0247) has been processing the upgrade requests and you can check to see where your new seats are by giving them a call. You will need to have your "Account Number" handy (which you can find on your "My Account" page on the MGoBlue.com site). Not everyone's request has been processed yet, but I got my new seat locations and I thought I would give the public service announcement to others in case you were curious.
Edit: Yes, I was happy with my upgrades. I upgraded 1 PSD tier, but I also asked to be moved as close to the field as possible (because I like trying to see the player's faces as opposed to those who like the higher strategic view). Anyway, they gave me Row 2, which I'm more than happy with (and I'm tall so I'm not too worried about the 3 seats in front of me).
