There are quite a few suppliers in Northern California. Koehnen is one of the largest producers of queens, and shakes alot of packages up there in Glenn. There are a couple more in Chico and I think there might be some in Red Bluff. I believe there is another in Marysville. I'm having trouble with names at the moment, but I'll add them if they come to me. Lots of options to choose from out there. These should get you started.
