When I was a freshman, we had Bastercard access to get into public buildings on campus after hours. Mines called itself an open campus at the time because of this. It was great because we could study at the school during weekends and use the rooms to meet with friends after homework or activities.
Now, it's a hit or miss on getting into buildings because there's no Blastercard access and you need to find a door that's been propped open. Let us access the buildings after hours again!
