I'm lucky to have seen a bigfoot as close as 10 feet away, floating on his back drifting along http://www.bigfootencounters.com/ Biddeford Maine. I'm glad it was years back because I didn't want anyone to go hunting for him. I believe they are beings of the fourth demension. Visible at times, difficult to kill, thank God.
I also believe they chose to live life as they live it now. Close to nature with few tools and mixing with man is not their thing.
I encourage people to leave them alone and honor and respect for them.
It's there wishes to be left alone and let them live there life the way they have done for many years.
