no one has here I don't think. I really doubt they well ever be found in North america though. not like there's thousands of miles of uncharted territory left. And if theirs. ahem... "There are only estimates. The informed estimates range from roughly 2000 - 6000 individuals for all of North America (which includes all Canada and southern Alaska)." If their was that many, I'm sure hunters would be tripping over them constantly no? none have been observed other then the (being polite here) Patterson film, no DNA gathered and analyzed by a reputable source, no foot prints that were not proven fake by actual anthropologist and zoologists...... it's safe to say they haven't been found yet.
