Roller skate group?

Was at Axelrad for movie night on Oct 30 when a huge group of roller skaters came in dressed in costume. It looked so fun and unfortunately when talking to some of them I didn't get the name of their group. I looked up on here but they were from a year ago most recent and i'm not sure if the groups are still alive. If anyone knows this specific group (i think they skate from bar to bar?) i'd love to join!

thank you 🙂
