Picked this geocoin up during a hike around the southern portion of Pleasanton Ridge, rather than in the centrally-located Monkeying around cache. I didn't keep very good notes of swag swaps, but I do believe I got this coin from my last stop, GC89DA. I would imaging someone doing the park the "long way" just moved it along on their trip without writing the number down to log it. It was rattling around at the bottom of a huge ammo can, in a nice old cache...
