Cache owners often seek creative ways to guard a geocache against the formidible muggles. And concealment comes in many forms: Hidden In Plain Sight, caches located inside a host container, insanely small and/or difficult hide style....you name it, it's been tried. This geocache has some of those traits, but you will just need to come seek it for yourself to find out which one(s).
Should be a quick find....for those that may have seen this style of hide previously :) If not, well...as with any cache hunt, keep your eyes open and geo-senses focused.
It is NOT located in the hollow end of the guardrail. Bees like to call that hole home. Bee careful.
