I voted more skill then luck. I've got some good buddy's of mine that hunt some prime whitetail grounds. Were talking booners in some of these areas. They don't have a clue on what there doing. Never have any of these friends of mine saw a buck bigger then 130" while bow hunting In all the years they've been hunting these spots. Every year they find a shed or two scoring anywhere from 60" to 80". This summer my buddy had a 170"+ targeted all summer on his trail cam damn near at the same time every 2 days. He also had 3 to 4 130" to 140" bucks on cam. He never saw any of these bucks. Why didn't he? He put allot of time In but he doesn't have a clue on what he's doing.
