i'm in west la. just moved out here from chino hills for work. i'm looking for a practice partner too. i have no idea where to play because i'm unfamiliar with the area! i think we might be at the same level!
Well, Roz and I played yesterday at the Sherman Oaks / Van Nuys park. there are nice courts there and yesterday there was even a nice group of people taking extra players, I expect they go often in the mornings. The park is pretty big and if you want to google it - the tennis courts are at the intersection of Addison St and Tyrone Ave.
