From his bio:

I dream of working from a 20 acre ranch in southern Oregon, near the town of Merlin. Right now it's just a trailer and a well. Now, I live with my wife, four children, ten chickens, two button quails, and a dog amongst the redwoods in rural Santa Cruz county, just minutes from the bustling, teeming Silicon Valley.
