There will be a stream at Noon for free on MGoBlueTV on what the "historic event" is at Michigan Stadium.
EDIT: It's official
Apparently tonight, the Bo Schembechler statue will be unveiled at Schembecher Hall. Tomorrow, the new Towsley Museum will be open to the public for the first time from 9am-Noon.
I'll be going in the summer to avoid the crowds of tomorrow.
