If you get to know some of the elite players and attend their pay clinic's or private lessons you can sneak on to courts at certain rec centers, on the occasion rec center employees come out checking ids and you are not on the court you will be ask to leave with no resident ID card. Some of the elite player even give lessons during open play times. IMO private lessons on Rec center courts should only be allowed if the rec center get cut of the pie and are at times when no courts are being untilized by residents, which means they have low priority. Volunteer free clinics are different and scheduled through the rec center. I have observed this playing at Rec centers.
