I graduated last may, so I suppose you could say I'm close enough to a current mid.
Yes, the buildings are old, and the reality is that most of the facilities aren't going to be as new and shiny as what you'll find at some of USNA's peer institutions (especially the private ones). I don't think this greatly interfered with my life or my ability to function as a student, and I think most reasonable Midshipmen would agree.
There are some issues though. MacDonough Hall is in absolutely pitiful shape. The Dungeon pool is atrocious, there's rust everywhere, the roof leaks when it rains, half the weights and several of the machines are broken. When you combine that with the fact that the 7th Wing Gym is in a similar state, then you could mount a fairly strong argument that the ability of the non athlete Midshipman to accomplish the physical mission has been compromised. It's quite difficult to watch Ricketts Hall, which only 10% of the Brigade is allowed to use, get renovated again and again while the facility that serves the majority goes years without so much as new paint.
I'd hope that the Alumni that decided to donate $20M to build the new sports hall of fame and recruitment center got a chance to read that report. Perhaps next time they'll decide to spend their money on something that'll actually benefit the Brigade.
