A letterbox is another form of treasure hunting, using clues instead of coordinates. Once a letterbox is found, instead of signing a log book, you place your stamp mark in the letterbox's log book, and place the letterbox's stamp in your own log book.
A letterbox hybrid has both a stamp and a log book, and coordinates are given, making it a geocache. You can leave your stamp in the cache's log book, and get the cache's stamp in your own log book, or you can sign the log in the traditional manner. Or both.
This letterbox hybrid contains: A log and a couple of pencils, along with a few small trade items. It contains a rubber stamp. Please leave it in the cache. Bring your own ink pad.
This old railroad grade was donated to the public by the Federal Government. It is open to non-motorized use: Walking, equestrian use, bicycling, x-c skiing, snowshoe treks. Dogs are welcome. With no vehicular traffic, it is a safe canine walking area. It actually begins west of this trailhead, and continues east to Farragut State Park, with several access points and a number of other caches along the way.
The cache is just off the parking area. It is a clear plastic lock'n'lock. Please rehide well.
Congratulations to Schweitzerguy on the First to Find!
P.S. I tried to muddle up the footprints by walking all over. You were too clever for me!
