That should work fine; let's make it the SW corner. FYI there's a pedestrian overpass you can reach from Rector street if you're coming from the subways to the east, just cross it, make a right on the far end, go down the ramp, and you'll be right there.
Speaking of subways, I just checked the MTA website, the 4 and 5 will not be running south of Brooklyn Bridge this weekend, so our best options will be the 1 to Rector St or the R to Rector St.
See you Saturday -
