Wait, @river_fox18, YEARS of granite dragging? That's insane.

Wasn't there a study about GPS drift on hiking trails? I remember reading that consumer watches can add up to 10% extra distance. It makes sense that your actual path would be smoother.

Nah, that turn is pretty clear if you're paying attention. I've done the High Sierra Trail twice and saw the sign both times. Honestly, a lot of people just get in a zone and stop looking at their surroundings. The real tricky spot is later on, near the junction with the Lone Pine Creek trail. That sign is totally faded and half-buried in brush.

Read a case study on automated quality control failing with textiles.

Reminds me of people who overthink cooking and ruin a simple meal.
