This is true, however,

A. This path will certainly be built in the future, as it is already in planning.

B. Portions of the mapped route, though not exact, follow well-defined deer and unofficial human-made trails through open forest. I chose not to share this detail before as I didn’t think it had any significance to the mapping of the trail itself, but since you brought up well-defined trails, I had no choice but to share it. If you look on Google Street View on Case Street at the northern end of Future American Perimeter Trail, you can just make out the deer trail as it heads in to Enders State Forest.
