The BisMan area needs more challenge caches, so I thought I'd provide some!
This cache is at the posted coordinates and you may sign the log at any time, however you may only log this cache as a find if you have found at least 500 caches and you have found the final container and signed the log. Lab caches do not qualify for this challenge, and this cache cannot be used as one of the 500 finds. There is no need to provide proof of qualification as I can simply look at your find count, however a link to a challenge checker has been included per Geocaching.com guidelines. The final is a park and grab. Please use stealth and BYOP. Happy Hunting!
