Thats amazing Flip. I have just been researchin Bigfoot the last couple of days and I beleive that this creature exists. Did you get that plaster cast?
I have looked at the evidence. I have reveiwed it with my brother who was interested in bigfoot since the age of 13. There has even been a recent sighting in manitoba. Twitches country!
The patterson footage has been analysed for the last 30 years and they cannot disprove it. I can go into greater detail but I beleive what you are hearing and seeing. It would be great if you could capture something on film or camera, if you don't shit your pants in front of an 8 ft. 6 Gigantpithicus with black eyes that smells like dog shit. Good luck in your sons quest.
