Re-Visted Fuller Road to explore one of the side-trails... decent forest path that just seemed to end at a small ravine.
I will re-check once the snow is out, but I don't expect to find much extension.
Ended with a "rough" 1.5-miles mostly due to more snow (hard and crusty) than I expected.
An additional positive from visiting this area is that I believe I saw a location to park to "find" Lost Acres Falls once the snow clears out.
