I really liked the segment in the turkey/ longbow episode where he sat down with the Primative Weapons Specialist (Or whatever his title was) at 3 Rivers Archery.
They sat down and Tred got a tutorial on making a flint arrowhead and he was so genuinely in awe of the process and wanted to be hands on I thought it was a great segment. He looked at the guy doing the work like he was inventing fire for the first time.

(By the way after knowing all the work that goes into a single flint arrowhead I wouldn't have the heart to shoot one. Seriously[:-])
