Free recording booth/spaces?

I usually go to the recording studio at OSU or the Westerville Library, but they're all booked out, and any available time slots are when I have to be at work. I found out that Columbus State has them, but I currently don't have a school e-mail/Cougar ID with them anymore.

Does anyone know if there's something like it that exists in Columbus? I don't need to use any equipment as I have a small interface, my laptop, and a microphone. I just need a quiet space suitable for recording.
