Always totally stuck in a massive block of people with no clear line of sight.... and then the mass exit - yuck.
I recall seeing the spectacular display marking the 100th anniversary of the completion of the Brooklyn Bridge. Lots of people were drinking and not an open restroom in sight -- it made me wonder.
i was there too and very young.....remember watching from around the seaport area as people peed off the elevated highway onto the packed crowd below!
