To answer the original question: No, not seriously.
Still awaiting some credible evidence of "urban bigfoot." This does not include purported, linked, yet not produced "casino dumpster diving bigfoot."
Reports? Sure. One can produce "reports" of urban reptillians, unicorns, and mermaids. Really? Reports are not proof.
The OP has mentioned purported audio encounters from a year ago, maybe he found suspect footprints, but what else? A "pinned" thread, and what has it produced? Rampant speculation, check. Facts, or even worthy evidence? Eh.
