Sounds fun: there's going to be grilling, music, a moon bounce for kids, arts and crafts, and general camaraderie. It's from 3-8 pm.
They also made an awesome poster, and here's the Facebook invite.
Neighborhood bars and restaurants are sponsoring the event, and it will only be on Meridian Place, not 14th. They've been doing the party for years now, and the Facebook invite has a lot of older photos of the area, which is pretty neat.
Sounds like a great event, hope to see folks out there. They even made a video!
