As the absurdly synoptic headline indicates, UM/MSU single game tickets are being sold at www.mgoblue.com - Here's the trick to get tickets together:
1. Open two different browsers (diff programs)
2. Navigate both to mgoblue
3. Select MSU game
4. Enter "1" for tickets desired
5. Do not click "Best Available" or a section. Select a specific section
In honesty it might take you some tries to find out what sections have back-to-back or parallel seats. I was able to secure Section 8, Row # and Row #+1, Seat 11 through this method. $75/pop is better than whatever exorbitant rate they're going to be going for if both teams come out swinging these next couple weeks.
