Public Swimming Pool Recommendations

I’m recovering from a hand injury and returned to lap  swimming at Dos Pueblos over the summer – beautiful pool! – and now they are closed. Where do Edhat readers suggest for lap swimming that won’t empty my wallet? A few things: If there is some instruction, nice, but not necessary; I don’t want an indoor pool; I tried UCSB and that doesn’t work for me (plus it’s pricey when you add the parking fees). Thanks in advance for the suggestions!
