This Cache is a simple Park~n~Grab. It is an easy one, basically here to help your numbers. I also felt that this corner needed a cache. You need to be a little sly, as the cache is near the exit of an automated car-wash. As usual with a png, byop.
Chevron gas stations used to use the name Standard, and in fact, the Chevron Oil company was known as Standard Oil of California. Chevron has one station in each state it owns the rights to branded as Standard except in Kentucky, which it withdrew from in July 2010. It appears the only station with the Standard name in California is located in the San Francisco area. And that is why this is a Standard Cache.
Congrats to Sparklette on the FTF!
