The part that I found most interesting was his discussion of one cast. Krantz claimed that simply scaling up a human foot would give you a cast that would be all wrong for a creature like a Sasquatch. He claimed that only a half-a-dozen people in the world would know the physiological changes in the foot necessary to support the great weight of such a large biped. He claimed this cast had all the necessary characteristics and was the one that really convinced him of Sasquatch's existence. (He gave me one of the duplicate casts of that print and autographed it.)
It was very interesting discussion. I left his office as a skeptic but less of one than when I went in. For the record, Krantz was convinced that Sasquatch is a relict Gigantopethicus, a giant biped ape of Asia which he thought came across the Bering land bridge.
I was saddened to hear of Krantz' passing. After all the crap he had to take from his colleagues, I was kind of hoping that the existence of Sasquatch would be proven so he could have the last laugh.

Gigantopethicus
I knew a guy that worked for the Washington State Fish and Wildlife. They would travel hundreds of miles to get hair samples off a fence, etc. where someone said they saw a bigfoot step over, etc. He said MOST of the time it was identifiable. But every once in awhile not! (I don't recall if they did DNA, and all that stuff on it or not>)
