Allow me to copy and paste...
Though Munn is old, it sets an excellent baseline for renovation.
The sightlines are already excellent, the luxury suites are pretty good, and the scoring electronics are fine despite being about a decade old.
If you put money toward expanding the concourse and the restrooms, build an high-capacity indoor ticket counter area, replace the rink and refrigeration system, rip out the fatigued lime green fiberglass benches and replace the old benches with chairback seating, add a practice facility with an olympic sheet, update the locker rooms, and, in general, make the place look less like a 1960s prop from a sci-fi alien invasion film, and you'll suddenly have one of the best facilities in college hockey again. It sounds like a lot of work, but it's really not compared to some of the other rinks I've visited in this league. The university has done a really great job taking care of the building, but elements of the facility are still straight out of 1974.
Following that, if you move the students down to the glass, drop the student season ticket price by 50 percent, and work a bit harder to promote hockey on campus, you'll suddenly have a great state-of-the-art rink with a good atmosphere that people (and potential recruits) would actually want to visit and experience on a regular basis.
It's not a necessity to pour a ton of money into Munn, but some funds need to be allocated.
