@ehBeth,
Yes, Humboldt Hill was just down 101 from the road up to the higher part of the main town area, Harris Street, where, when I was first there, my soon to be business partner had at that time a garden center..
I lived for a month in a rental place, while I was looking for a house; that wasn't all that far from the Humboldt Hill area - but soon I was mid town, very walkable to Old Town,
Small world.
