This is the kind of item that gets a professional surveyor excited.
The DNR's Matt Dontz found this original cedar survey post in a stream near Atlanta, in Montmorency County recently.

It was preserved by the water, Forestry and Surveying experts agree the find is extremely rare, even with today's GPS technology.
We've seen add-ons for locks to try and make them smarter, but it's about time the locks themselves gained some intelligence. Kevo ($TBA) is the first we've seen.
