Burrs... Nature's excellent system of spreading seed pods far and wide. If you are a longer haired cacher or cache with a geodog, these can spell hours of frustrating removal. Consider yourself warned!
Congratulations to Buttons and Capjap on their shared FTF.
BYOP.
May 26th update: WARNING - we did the trail today and saw a patch of GIANT HOGWEED near the trail head. Though we did not encounter it further down the trail or near any of the caches, be aware that it is in the area and should be avoided!
