I remember 9/10/2001.
It rained all day in New York.
The day before I had almost gone swimming at Lake Awosting, except the park ranger blocked the path to the old granite swimming hole. No one was allowed in the lake after Labor Day to avoid legal problems.
There was no one swimming at the Coney Island or the Rockaways on 9/10/01.
Rain and a lot of it.
I recall turning on the TV and seeing the weather report for the next day.
Sunny cloudless skies and that sounded lovely to me.
