There are a couple of pools I would recommend: Both of them have Masters swims. They are both $7/swim during open swim hours. The Plunge @ Mission Beach Masters swims are Monday & Wed @ 6:30pm & Tues. & Thurs. @ 6am. Parking is tough @ The Plunge after 12 pm because there are hords of tourists here right now.
also, in the UTC/La Jolla area, the JCC (just north of La Jolla Village Dr. on Genesee) has masters at 6, noon, and 6pm (the 6pm just started so it isn’t on the webpage). Very good. $10
You folks should check out http://www.swimmersguide.com/query/Main1.cfm. It tells you where any pools are in the world, maps, phone numbers, rates, pool types, etc. etc. etc. I use it when I travel and have found 3 pools I use regularly.
