This geocache is loaded with GOLD (and silver, bronze, copper, et al.)!! Starting off with foreign currency from all over the world, so bring your own currency to trade! I hear that the exchange is pretty favorable right now, so seize the opportunity! 
All of the nearest parking is for a fee, but free parking can be found east of Harbor Drive. High muggle factor in this location, especially from the windows adjacent to GZ! Bring your A-game stealth to this one, and BYOP. Be sure to conceal the geocache well with natural material to keep this one going.
