Okay, we seem to have a consensus. Saturday works better for some, and while starting at 4 is a bit late, I'm personally looking forward to working some architecture during twilight.
To that end, if you'd like to join me, I'll be at the Roosevelt Island Tram station at 60th street and 2nd avenue this Saturday 10/22 by 4pm. I'll be at ground level, on the edge of the little pocket park on the south side of the block. If for any reason you need to reach me, my cell is (347) 880 - 0527. If you plan to attend, reply here on the group so I can get a headcount and we don't leave anyone behind.
cheers,
Steven
