Genuinely interesting pattern you've picked up on there. I dont follow Dogman cases as closely as some here but from what I've read, logging roads make a lot of sense as hotspots - old growth disturbance, isolated terrain, and the roads themselves create corridors through otherwise dense woodland. Same principle applies to a lot of cryptid activity when you map it properly.
What gets me is the overlap with ley line data in certain American cases. Some of the Pacific Northwest sightings cluster in ways that don't feel random when you plot them. Whether that's coincidence or something about the land itself I couldn't say.
Has anyone actually overlaid USGS topo maps with reported sightings and cross-referenced against historical logging activity? That kind of analysis would tell us a lot more than anecdotal clustering. Be curious whether the UK has any comparable patterns on old forestry commission tracks because we've had our share of strange encounters on them too, particularly in areas like Kielder and the Forest of Dean.
