Presumably they know who rode it there (unless someone carried it as a determined prank) so I don't know why they don't define what is and isn't allowed and tack on fees for less suitable locations. Or discounts or even rebates for claiming one from an odd place and riding it to a high demand one, almost like the scooter companies do for charging.

Apart from pranking the system, also unclear "why" - I guess you could get out to the thruway about there. Or looking at the map there are houses just through the trees to the west that seem to have only roundabout road access to the north or south, maybe someone who lives there and usually bushwacks to the trail as a shortcut rode it to their point of departure and planned to ride it back out again the next morning.

Or maybe it was broken - didn't look it, and that part of the path is very smooth so pinch flat looks unlikely, but possible.
