Many on here say this is why they shoot feathers. (No plastic bird wings.)
How many trees are made of carbon and fiberglass?
Do you have a string made of sinew or dacron?
Any aluminum or steel on your bow?
How do you glue your feathers on your arrows? Man-made epoxy? (with a steel, aluminum or plastic jig)
Then again, how about your nocks, are they plastic like my vanes?
Just thinking out-loud, nothing personal towards anyone.
If you ride a mule to your favorite hunting sight, wearing buckskin clothing, shooting an all wood bow with no epoxy, and all natural arrows, with no man made materials whatsoever on anything you own, then please ignore this message.
