Basically, it's like a gigantic sidewalk sale. All the streets are closed to traffic, the stores stay open late & have sales, the restaurants & bars have patios & specials and there are a dozen stages set up throughout the area. We will be on the Dunn St stage (Dunn north of Lakeshore) playing four sets between 7 and midnight.
