No reliable, valid evidence. We've had 45 years since Patterson-Gimlin to prove bigfoot beyond the shadow of a doubt, in the way Dian Fossey proved the mountain gorilla in Rwanda, or Jeremy Wade proved the glyphis shark in NorthWest Australia. Bigfoot? Grainy, shaky, out of focus, long distance, brief video clips. Bigfoot is a myth.
To quote the ravings of Rumsfeld;"There are known, known's.There are unknown known's. And there are unknown,unknown's!And they could be North,South,East,and West of us! LOL
