To get there from the East Side, go west down Wickenden Street (towards the river), pass over the Point Street Bridge, go through the light, take a right at the stop sign (onto Richmond Street), then take the next left (onto South Street). Nick-a-Nees is the rectangular building with the mural on your right.
Last time I think my friends were there mostly from the middle of the first set to the end of the second set (9:30-11 or maybe a little before) -- does that sound about right? When we talk about the set list I will try to move up some of the material that we saved for the third set last time.
Also, I'll probably be out tacking up posters on Wickenden Street tomorrow (Sunday) or Monday if anyone is interested in joining me.
