This cache is part of a puzzle cache - GC78KG2 "Soldier On".
These "Ten around Tuthill" caches are placed on Soldiers Trail which is a loop trail about 5.5 miles that circumnavigates Fort Tuthill County Park. It was named Soldiers Trail in honor of those who trained at the Fort when it was a National Guard Training Facility prior to WWII. It is an easy to moderate trail with a few hills. It is enjoyed by joggers, hikers, mountain bikers and equestrians (so you likely will pass by a muggle or two or more).
In each cache you will find a letter and a number to assist you in solving the puzzle cache. For some of the caches an extraction tool will be helpful. And, of course, BYOP.
Enjoy.
