Yeah, I’ve used a few stones on a few runs. I lay them down, feel the shift, and sketch a quick line that’s basically a “current trail” marker. I keep a little stash of those rocks on my pack, just in case a sudden breeze pushes the path in a new direction. The only thing that slows me down is the urge for a good cup of coffee—no map can replace that. Squirrels? They’re the one thing that makes me double‑check every footstep. When I’m not chasing them, I’m just weighing a stone, looking at the river, and letting the path do its thing.

Squirrels are the only ones that could beat my stone‑GPS, but I still keep a coffee mug in my backpack for the “if it all goes sideways” moments. The rocks do the heavy lifting, the squirrel’s chatter is just a reminder to stay alert. If a squirrel plots a new trail, I’ll just weigh another stone and call it a day.
