Should be a very easy find, in between my two favorite flea market destinations. Sparks & White Cloud KS "communities" (I use communities loosely because Sparks is a tiny intersection with a few houses that is considered an unincorporated town) host their twice annual flea markets on the first weekend of May, and Labor Day weekend in September. Also nearby is the ghost town of Iowa Point. Very unique little corner of the state, maybe this cache can help you on the county challenge, or Delorme, or at least the calendar challenge. I come to the flea market twice a year, when I will also check on this cache. Past incidents of flooding prove that this one isn't flood proof, every time the Missouri floods, so does good ol' Hwy 7.
Should be super easy to find. Congrats to grogg-kc for FTF!
Stealth is appreciated, because the cache is so far away from home, I don't particularly want to make a special trip up just to check on/replace it. Probably won't be an issue because it's awfully rural, but... there is a house around the corner, and I placed when a farmer was in the field nearby.
