I noticed this too. I'm on the upper east side and when I went out for a walk in the morning a lot of people are gathering in the park with their dogs like usual. I was running to the store yesterday and there were so many people on 1st Ave and hardly anyone was practicing the 6ft rule.
I want to go out today because its going to be 75 out, but I'm afraid that a lot of people will head out too. Its a tough situation.
