I was wondering if anyone had any favorite quiet, secluded locations outside of Los Angeles where they like to record. The ideal place would be reasonably quiet and away from spying eyes. Thanks.
I would investigate around the outskirts of Palmdale.
Speaking from a bit of experience, you are going to experience urban noise pollution even at great distances outside of Los Angeles County. Between the freeways and flight paths you'll be fighting the noise at every turn. If you really want to find a (relatively) quiet space I'd head for Death Valley.
Here's where Charles Maynes records, he says it's near Burbank: http://www.youtube.com/watch?v=uL350lOQ8I0
BTW, I can swear that there is a point in desert where many Hollywood gunshots get recorded. I've seen this picture of a desert with a faraway mountain (where they get the slapback i suppose) several times, but maybe all deserts look alike?
