Who doesn't love a good Geocaching Challenge Cache? I really enjoy working on various Challenge Caches, as it usually gives me a good long term goal to look forward to. There is a nice wide pullout next to GZ. You are searching for smaller camo lock n lock, large enough for Swag and Travel Bugs. The Difficulty rating is based on the requirements to log this cache, the hide itself is pretty straight forward. Please re-hide the container exactly as you have found it. Happy Hunting, and enjoy the Challenge!
