I have posted this question because just yesterday I went to a hotel/gorgeous roof top bar in NYC, but I called first and asked.... when the manager of the Bar said to me "You cannot take professional photographs here or you will be thrown out".... I was guessing that he meant "expensive equipment, i.e., lighting, tripod, etc." I was taken aback, but when I actually went there with my camera (and only my camera)... there were TONS of people taking photos... SO, I have this really cool shot of this place and am wondering if I can post it here on FAA and sell it here??? What do you all think?
