Time to hit the sheets, but first a little history trivia about the LA area and the Inland Empire. For a few hundred years, all this area was known as "the valley of the smoke" by the native Americans (Indians) here. LONG before any autos or industry. Much of this "smog" is a natural inversion layer because of our mountains surrounding us.
A friend of mine I met street racing in the Hemet/San Jacinto area in the '70s moved to Washington state around the Shelton area. I went up and visited him about twenty years ago. I don't know how he can stand it. It's pretty, but it's WET.
