anyone know why there were like 3 helicopters circling around 10pm last night

Mosquitoes spraying!

Yeah I think they were spraying for mosquitoes

Heard they were spraying for mosquitoes but I think that was the night before last

heard them too, thought i was losing it

If one had a searchlight going it was NYPD aviation looking for someone. They circle a grid pattern. If they were just crossing, could be medevac — the hospital helipad at 68th by the river gets traffic at all hours
