I think Asbell's point is similar to that of Peterson's (see Man Made of Elk), Mitten's (One with the Wilderness), and the Wensel Bros. (various) that hunting is about the chase and being close to Nature, not necessarily about killing the biggest bucks to brag down at the lodge about. Some folks think it should be done with the most primitive tackle, hand fashioned, and simple. Though I do not believe this is the case (I use a modern reflex delfex longbow, made by Damon Howatt/Martin, carbon or wooden arrows, astroflight skinny string, carbon steel broadheads, and synthetic limbsavers) I do believe an intrinsic part of the traditional bowhunting experience is the practice of woodsmanship. Learning to read sign, tracking, stalking, learning food sources, plants, prey animals, geology, basic meteorology, etc... that is (or should be) a separating factor.
Recently I saw a product at Cabela's that just make me shake my head... a tree stand umbrella... frankly if you need an umbrella to go hunting, maybe you should just stay home....
I think that's what these gentlemen are referring to as they discuss 'traditional'.
And for the record, anyone who does not bring a cell phone into the woods today is not thinking straight. Accidents happen. Getting lost happens. That phone can easily save your life. I consider it essential survival gear.
