Are they going to be allowed to use it? Or has ResLife/ParkingServices/classics & world religions booked it for the next 6 weeks for ???, ???, and ???

It was one of the first things Solich mentioned in last night's press conference, so he obviously thinks it will make a difference:

“It’ll be great to get back there. Now that we have an indoor practice facility, I think that does make a difference in preparation for the game in Detroit. When we didn’t have an indoor facility, we practiced outside and then we went indoor and had guys cramping up. It is hard to condition and get your team ready to play indoors if you are practicing outside all week. Having an indoor facility will be a big advantage for us going in to the game and for Toledo and Western, whoever wins that game. It’ll be neat to get prepared to play indoors.”

The indoor facility has had a huge impact on our program. If nothing else, it was a step that got us up to at least the middle of the pack in the league from a facility standpoint. We are still behind a number of schools, but we are no longer the bottom feeder as far as facilities like we were when Frank arrived.
Amazing that we did as well as we did Franks first years before the up-grades began.
