I am acquainted with the publisher. They do indeed specialize in California, especially in the Central Valley. Malcolm is a very nice man; more importantly, he is very effective at what he does. He attends all the trade shows and some of the book festivals. Plus, he gets good publicity. Several of his books have been reviewed by the Los Angeles Times. I have perhaps ten Heyday books on my shelves. All well written, well designed, and well edited.
