A few years ago there was a article in New York Magazine published an articled title Unmasking D.B. Cooper where they make the case that Kenneth Christiansen is the infamous D.B. Cooper.
This cache is in tribute to D.B Cooper and his ties to Bonney Lake.
The boys and I made quick work of the cache. It was a rock wall cache meaning the geocache is hidden somewhere in a 20 foot long rock wall. I really don't like rock wall cache but this one wasn't too bad.
