As far as bowhunting- I would have to say first and foremost it would have to be the folks who occupy this web site !
Second and not by the least whatsoever it would have to be 5shot. I met him on this site a few yrs back when I first took up bow hunting and then found out he only lives a couple hrs. away from me in Virginia- I live in West Virginia. After several trips over to see him , his wife Kim and his young son Matt over the past couple years I consider him a good friend and trust his advice- he has taught me quite a bit about setting up bows and archery in general.
