For an hour drive, Oak Quarry in Riverside is pretty spectacular. Black Gold in Yorba Linda is nice. Avoid OC, overpriced for what you get.
For the LB Munis, I'd rank them El D, Skylinks, Rec Park, Lakeview. I've heard pretty good reviews on Destroyer but haven't been there.
It is maintenance season, so check greenskeeper.org to see what courses are being aerated.
