yeah, our upstairs neighbors and my wife and I had dinner in the backyard, just the four of us, on Memorial Day. But that's it. We've all been locked down and hardly go anywhere, so it was pretty safe. Thankfully new infections/hospitalizations are way, way down in NYC and we are hoping that it'll stay that way for a while.
I would say masks are about 50%. Clusters tend to be around 5-6 people max in the parks; I wish more would wear masks, but... it's nothing like Lake of the Ozarks or anything, either. People do spread out. They could do more, but it's not outrageous. I think younger people here are pretty much steering clear of their aged parents/grandparents. I dunno, I'm cautiously optimistic but there are always those people who don't heed state and local orders, even around NY. I do worry about tourists from other areas of the country bringing the virus back to the city, which is kinda why I hope that most of the attractions stay closed throughout the summer.
