Tracking bigfoot

It was our father's dying wish to publish his book called Tracking Bigfoot. Our father Donald Lee Wallace was man who lived in the North Cascade Mt. for the past 30 years. He tracked Bigfoot for the past 28 years. He lived off the land and appreciated each day God gave him. I believe that due to the years of living in the Mt. and a trapper before that made him an expert when it came to reading the woods. I remember walking down the trail with our dad to go fishing and he would point out different tracks by the animals that live in the woods.
