Bit far from my patch in Hampshire but I've been following teh Appalachian reports for a while now and the track evidence coming out of that area is genuinely interesting if you know what you're looking at. Dermal ridges are the thing to look for - any muppet can fake a big footprint but replicating realistic dermal ridge patterns in soil is another matter entirely.
What are we talking here, five-toed bipedal with mid-tarsal break or something else? Because that distinction matters a lot and most people don't bother to document it properly before the cast dries wrong or some dog walks through it.
Post photos if you've got them, ideally with a ruler or something for scale - you'd be amazed how many people submit "massive" tracks that turn out to be a large black bear with some toe drag. Not saying that's what you've got, just saying rule it out first before we get excited.
