Never looked into dogman much before but this got me thinking. We've got old railway lines running all through the bayou out here and theres definitely something off about those corridors at night - always assumed it was just the usual Louisiana weirdness but maybe worth paying more attention.
The railway connection is interesting though. Old lines often follow ley lines or natural waterways, and animals (regular and otherwise) use linear routes through terrain. Makes geographic sense that something territorial would patrol a consistent path.
Anyone mapped the sightings against the age of the lines? Like pre-1900 vs later construction? I wonder if the older routes follow something that was already there long before the trains came through. Wouldn't surprise me at all if indigenous communities in those areas had older accounts that predate the railways entirely and the line just happens to follow the same ground.
