I have two courts in my apartment complex (by the boardwalk on the Hudson) that I can book an hour at a time, and best of all, during the weekdays, they're generally free all day.
I'm pretty decent, can rally hard, I'd say I'm definitely a 4.0. Maybe 4.5? You'll have to tell me...
Anyway, if you're about 4-4.5 range, love to hit to improve, and you can play early in the day especially, during the week, give me a shout. I'm a teacher and have about two and a half weeks of vacation left!
