Found this while looking for more on the hernia and how it was noticed:
"In 1998, Hajicek contacted the Bigfoot Field Research Organization, and began the early work on what would become Sasquatch: Legend Meets Science. John Green lent him his first generation copy of the Patterson/Gimlin footage, and Hajicek had the film cleaned up and transferred digitally to a computer.
He quickly determined that there wasn't enough, with the P/G footage alone, to fill an hour documentary.
He spent hours in his basement looking at the digital footage on a High Definition monitor, concentrating mostly on the head of "Patty", when he began to notice a bulge, which appears then disappears on the right leg of the animal. He later discovered that there is an injury, which occurs predominately in women, called an Erectus Femoral Hernia, which is very similar to what can be seen in the P/G footage.
As part of the documentary, he shopped around and found a forensic animator willing to create a "digital skeleton" by "reverse engineering" from the footage. (The first bid came in at $300,000, another was $100,000, but Hajicek, due to budget constraints, was forced to take the lowest bid.)
The result was a skeleton, which appeared to walk in a manner completely different than the movement of humans. The knees would bend, with the legs splayed outward - then the knees bend in, in a knock-kneed fashion. The Peruvian-gait Horse (bred to walk up hills) is the only animal Hajicek has found that exhibit this manner of walking.
His conclusion - "No suit in 1967 (or today) could create this effect."
Other things noticed in the digital P/G footage:
The hair appears to bristle when Patty looks at Patterson and Gimlin.
Patty seems to favour her right leg.
A scientist (who was sure the film was a hoax) agreed to watch the digital footage and was able to identify 40 different muscle groups on the animal. He couldn't give any explanation how that could be hoaxed."

Check out Crypto. There are articles on everything from putting together a conference (no huge speaker fees noted) to bear tracks and misidentification. I hadn't seen this before. Ain't Googling fun?
