There is a "Target opening by end of 2017" location on Tesla's Supercharger map, labeled "San Felipe". It is on Hwy 152, east of Gilroy and north of Hollister, where San Felipe Road intersects 152. San Felipe is not a town, it's just an intersection out in the country formed by a road named San Felipe. I have driven 152 many times and I don't know where Tesla would place a Supercharger in that area (of course Tesla's site location marker should not be taken as the exact location of the Supercharger site). There is a small market at that intersection -- I think it is just a seasonal fruit stand, there are several of them along that stretch of 152 -- but no other commercial establishments that I can see. Below is a Google Street View image of it. So let's keep an eye out for any signs of Supercharger construction in that general area! It will be a very useful location.
