I thought I now knew what to look for and had my suspicions confirmed by Team Nut Tree. We met at another cache in the park and he offered to help me find this one. Found my white feather then ventured out further. Hmmmmm, Yup- Got it!! Nasty but Not as tough as the 5 difficulty suggests- Extreme. This was found within the acceptable zone of error at GZ. Not sure how I missed it last time. Team Nut Tree said it was better camoed then when he found it. I was the first to sign the new log. Thanks for the help Team Nut Tree and thanks for the cache GeoRoot24.
