Good old Fred Bear.
Those old guys pretty much had to learn everything by trial and error. The entire traditional archery world owes them a huge debt.
Little known fact: Fred Bear was a user and proponent of poison pods. Felt it was more ethical to use them, but would result in just about any hit outside of hoof or horn being lethal.
those were legal for years in Mississippi, might still be. They work, I know one deer that was shot low but caught the leg muscle below the chest killed the deer within 100 yards. The drug used is also used on people for some things to relax internal muscles, or that was the drug used in the 80s. I had some back then and pods to use it but never got a shot at a deer I wanted to shoot when hunting with it.
We as archers today we owe a lot to those men and not just the Trad archery group, some like Fred bear were supporters of the compound though he never switched from the Traditional archery. Part of their goal was to grow the sport. A lot of the Fred Bear video collection was put on Youtube.
