You might want to look into a Thousand Trails Zone Pass. There are 17 TT parks in California including Palm Desert, Pio Pico (near San Diego), Soledad Canyon in Acton (in LA county near Lancaster and on the MTA rail transist line to downtown LA, Santa Barbara, Yosemite Lakes, Descanso (near the Monterey Bay), Ponderosa (in the Gold country near Sacramento), Minden Lake (in the valley rice country North of Sacramento), Snowflower (in the high sierra along I-80), Russian River (in the Sonoma Wine Country). There are 3 more that I can think of in Ca that I haven't mentioned.
