Saw one on the train a couple of weeks ago. It was raving and angry and waving a glove around in the air. I quickly made my way back to the 1st class carriage and the rest of the journey passed off peacefully.
No, I don't believe. You can put Bigfoot in the same category as the Loch Ness Monster, Chupacabra and the Yeti. Tall tales to scare children and fool the foolish. Next you will be saying there was no moon landing and 9/11 was sanctioned by the CIA.
