I'm always busy Thursdays, but pretty much any other day works. With the other weekdays I'm free in the afternoon, and Friday I'm free all day. Most weekends are good. You have a day in mind next week?
I play in Inwood, and Washington Heights which always has empty courts, but it's on the northern tip of Manhttan so I think that would be asking a lot of yah. I know a court in Brooklyn next to where I go to college which we could try, but it might be crowded or there's a small chance they might kick us off. If you don't mind taking that chance then we could try Fort Greene Park.
