Jackhammer on Thursday

I’m going to be in Chicago this week and I’m thinking of checking out Jackhammer on Brief Encounters night. I’d be going solo. What should I expect? Do you have to be in white briefs? Do they have lockers? (I mean, it’s going to be cold this week🥶.)

I’m 47 year old bi-bear. Tend to be more of an introvert, so I’d be stepping out of my comfort zone.
