Mother Nature's A Literal Bitch
From Geohashing
Consolation prize for being prevented from reaching geohash by local aggressive fauna, such as dogs, boars, or raptors. Only counts if said fauna was guarding land that would be legally accessible for you, otherwise go for No trespassing consolation prize.
While I haven't quite encountered such a hash yet, one of my expeditions could have progressed a bit further if it wasn't for a couple of stray dogs keeping me out.
