In the town, of Menlo Park
Is a cache, placed by me
It's not a Diffictuly 5
It's closer to a D3
With many muggles abound
If you use stealth, you won't be seen.
GZ is yellow, the cache below.
Hence the name: Yellow Submarine.
Congrats to JuniorWences on FTF!
Note: this overpass isn't completed, they might do a bit more work on the surrounding area, but that shouldn't make the cache irretrievable.
