As you know, you are in a sparsely populated (relatively speaking) area of CA. You might find some nugget hunters up that way though. Also get on the kinzli CA forum, and perhaps some CA coin/relic hunters from that far north in CA might chime in .
There's a dealer near Chico, but he primarily deals to prospecting/nugget venue of the hobby. But he may know of coin/relic type md'rs up your direction.
