My wife and I are both 3.0 players. We play 3-5 times per week out at the awesome Diamond Hills tennis club in Oakley.
Anyone care to join us for some casual competition? Single or doubles, we're game! :) We're about 20 minutes from Walnut Creek, out Hwy 4.
We string racquets too, by the way. Our info is online at MyRacquetDoctor.com.
