Been tracking Bigfoot reports along the old Illinois Central corridor for about twelve years now and I'll be honest, the rail line correlation keeps nagging at me across multiple species accounts. The Dogman cases are no different. Old rail lines follow ridgelines, cut through bottomland, and were deliberately routed away from populated areas back when they were built, which means you've got long undisturbed wildlife corridors that have been sitting there for over a century in some cases.
The Louisiana and Mississippi reports I've cross-referenced show a clustering pattern that's hard to dismiss. Not every sighting is near a rail line obviously but the concentration is statistically notable if you bother to actually map it out properly instead of just collecting stories.
My theory, for whatever its worth, is that these corridors function as travel routes. The vegetation cover along abandoned lines is dense, the human foot traffic is minimal, and the terrain is predictable over long distances. Any large undocumented animal with any intelligence would use them.
Has anyone done proper GIS mapping on this? I'd genuinely be interested in pooling location data.
