Donors were offered UCONN, PSU, NW, IOWA back in May. The highest level of donors were also offered MSU. I know UCONN and PSU sold out the allotment already. I am not sure about NW and IOWA. I would imagine those are sold out too if they have yet to be offered for public sale. You could call the ticket office to ask about NW and Iowa. I am pretty sure that NW and Iowa may be selling single game tickets for Michigan on their respective web sites.
