Once in a great while in the past couple of years I've had to wait for one of the building's four shower rooms to open up. This spring I've had to wait more often. Today, there were actually other people waiting with me.
It's a good sign as far as the popularity of commuting goes but it's not something I've built in to my schedule. I might have to break down and get up... early.
Another advantage to riding in the winter I guess. I never have to wait for a shower on those -20 days.
