The jam will be at the usual time this Sunday, 1-3 PM, but will be in Detroit at the Concert of Colors. We've danced here before, and it's always been a blast. There's a great grassy area, sometimes with a tent for shade (so bring your sunscreen just in case), then tons of food, music, and standie-uppy dancing to follow. It's at 3711 Woodward Avenue, The Max.
Here's a map.
