M9L provides music, a vibe and lots of self-guided puzzle hunts. Bring a smartphone, headphones or a portable speaker, your own pumpkin and carving supplies, decorations, a yoga mat and whatever makes the park yours. There’s also an informal singles mixer.

Event speakers stay at the UFO during the day. Sponsor areas may add decorations and speakers. Check the day-of map for active areas, quiet spaces and event support.
