Super sucks!! From Santa Cruz but also working once or twice a week in SF; will keep an eye!
I'm so scared on having my 60 being stolen (not here on the west side in santa cruz) but more on Mission district where my company is that over the holidays I looked at ways to make it harder for people to steal it (just started that process): I installed an hidden ignition kill switch, and always park with the transfer case in neutral (tip I got from here). Yesterday I was there all day and all night until early in the morning and I always walk back wondering if someone stole it or not.
Considering putting some sort of bluetooth gps tracker as with the population density a cheap system like TrackR or Tile should work pretty well; see
The best GPS locators, finders and trackers | ZDNet or more expensive
Best GPS Trackers for People, Pets, and Possessions.
Again I'm super sorry as it does suck; will look for a red 60 with your
7CHA167 license plate.
