Astoria represent. I have lived in Astoria going on 13 years now, not sure I'll ever leave. I have enjoyed many a puff in that park and enjoyed the pool many times as well. If you want a special experience for the Astoria Park fireworks before the 4th of July, walk up to the peak of the Triboro, the fireworks burst right in front of you.
I have vaped in the AMC theatre, taking tiny hits of pure BHO from a cartomizer and holding them until nothing came out for "touch ups" during a feature.
NYC has always been pretty cannabis tolerant in general. Back in the 90's when I was a teen, I would walk through the heart of Manhattan smoking joints right past cops and they didn't seem to care.
