Fascinating thread this. I don't follow American road corridor sightings as closely as I probably should but I've always been curious whether Dogman clusters follow infrastructure the same way some Black Dog legends do over here in the UK.
There's a theory I've come across a few times that these things move along river valleys and freight routes, almost like they're exploiting the same pathways wildlife has always used. Does the I-70 corridor follow any major river systems? That might be worth looking at on a map before assuming the sightings are random.
What's the rough timeframe we're talking about here? Last six months, last couple of years? And are these mostly rural stretches or are any of the reports coming from near towns and service stations? That detail tends to get lost but it matters quite a bit when you're trying to work out behaviour patterns.
Anyone cross-referenced these with BFRO reports from teh same area? Sometimes the two overlap in ways that raise interesting questions about what witnesses are actually encountering.
