More than you want, or need, to know about NFA
NFA refers to a user...me...and also to the Northern Forest Archipelago...a micronation located in the Northeastern part of North America, with the US.
NFA the geocacher, has been caching since 2004, and loves it more today than on his first day of hunting for crap hidden in the woods.
