GC559M6? Published 3 months ago it has 90 finds and 12 favorites. Are you certain that the hole was installed by a geocacher? As some utility poles have holes already.
It seems that since Mingo isn't buried anymore, nobody has destroyed it since then, so we shall see how long this one lasts.. In the meantime it will get plenty of visits and some will probably copy it, with the reviewer saying they aren't a cache cop...
The caches near Mingo are pretty safe and are well known by the locals. Many times when my nearby cache GC4K4QN gets found, cachers are often greeted by the locals and they talk "geocaching. Even the guy who mows the ditches is aware of them
