Should have headed one valley west.. to the Healdsburg valleys. Nice biking. It used to be a great region for growing hops.. and a few miles north is a place called Hopland. Here in Healdsburg there is a winery that is called Hop Kiln. Gives you an idea of some of the hop history here. But, sadly the hops developed problems due, probably, to the humidity levels we can have here.. and other things. Was not profitable. Napa valley is probably a bit less humid as it's a mt range further from the ocean. But, some of us successfully grow some hops here for fun.
