Blossom Hill Road is mostly in Los Gatos, actually. The LG city limits go almost (but not quite) up all the way to Camden Avenue, shy by several long blocks. The vast majority of the Los Gatos is east, not west, of Hwy 17.
and yes, a nice neighborhood all of it really.
not your urban slum....
Forgive me...my sense of direction might be screwed up here but as I recall, 17 runs from the Santa Clara valley east and west with LG being on the northern side of 17...at least, that’s how I remember it growing up there from 1963 to 1977....
