I think we met at about 3pm at Pier 41, took a 1/2 hour boat ride and stayed until 9pm.
The rangers were great, gave us all kinds of access that you don't get on the regular tours, including the basement with no light at all! Very spooky. K&S had lots of equipment for people to borrow.
It is definitely more of a MF trip, we were moving too fast to do any LF, although the last hour was spent wandering solo.
I'll look out those images and post them
