It's a quick two-stager for all of the people trying to fill their calendars, and those that are afraid of multis. There are no tricks, and nothing fancy. There's even a checker to make sure your coords to S2 are correct!
At the posted coords you're looking for an electric box. There are "SW#" stickers on all sides.

Let a = the total number of "SW" instances on the box.
Let b = the number of "SW1" instances on the box.
To make coords for S2:
Use the posted north coords: N 38° 39.606, and SUBTRACT (a - b) from the 606.
Use the posted west coords, W 121° 29.760, and ADD (a x b) to the 760.
The final coordinates should be nearby; within walking distance.
