Harbor City Roller Derby (HCRD) are playing their second home bout of the 2026 season with Mayday Mayhem. HCRD will take on The Dirty Ores on Saturday, May 30th, at the Duluth Heritage Center. HCRD is harvesting the power of our great lake and going full out nautical. Expect crushing waves, monster hits, and a bout fierce enough to wake the deep. This isn’t just a game, it’s a full-blown sea battle. Doors open to the public at 5PM and the fun starts at 6PM. Tickets are $15 at the door and online at https://www.showpass.com/hcrdmm/. Kids 12 and under are free with a paid adult. This is an ASL Interpreted Event.
