Today is the start of Bike! Bike!, a gathering of bicycle cooperatives from all over the US.
From their site:
Bike! Bike! is an international annual conference organized by and for Not-For-Profit bike projects. It takes place in a different city within the United States each year (perhaps it will expand to one of our neighbors one day?). This year it will be hosted by the Grease Pit in Minneapolis.
