IowaBeaver: In the two and a half years this has gone unfound, the critters finally got to it. I could see the cap missing as MM2 went up to the cache. He verified the cap was missing. I looked down and spotted it on the ground. MM2’s son retrieved the cap but it was severely chewed. I decided to go ahead and remove the cache and archive the listing.
Thanks to all those who ventured out here.
