Purpose: This cache is about having a walk in the woods, exploring a trail system (trail goes right by cache), enjoying nature, and a creatively themed cache. If that sounds fun, this cache is for you. The challenge here is your don't know the size.
Rocks nor roots will help you sign a cache. Better bring a pen.
Look closely at the PR you're spinning mister.
Congratulations to XLG for the FTF!
