porterhouse:
I looked up all of Cali just to be sure. I may have missed some but here's what I found.
Airports currently served by NDB approaches (according to the NACO terminal procedures) in Socal include: EMT(El Monte), WJF (Lancaster), SLI (Los Alamitos Army Airfield) and SBD (San Bernadino,formerly Norton AFB).
Up your way, it appears you'll have to fly all the way up to SIY(Siskiyou county) to find one. Yeah they've really cleaned out NorCal of NDB approaches!
