Wait, you actually trust the GPS over a wall that's been sitting there since 1907? I've had the same thing happen more times than I can count, and honestly the paper map wins every single time. Those old surveyors knew what they were doing, they marked stuff on the ground that's still there, unlike these modern satellite overlays that get shifted by tree cover or road work. Phones are great for finding a Starbucks, but out in the sticks they'll put you in a goddamn pond half the time. I always print the plat map and carry it with me now, then use the GPS just to get close and eyeball the rest. You gotta respect the old lines, they didn't have drones or satellites, they used chains and compasses and they were dead accurate.
