It's not that simple. For example, I think finances have a lot to do with a lot of guys' success in the field. That's one aspect of "hunting" that is oft-overlooked. Any schmuck can fork out $3500 for a fully or semi- guided hunt and kill a PY class animal every year. Or they can easily buy 3500 prime acres of whitetail habitat and wallpaper the place to help bolster their odds. So add "Money" into the equation.
Same thing with retirees and guys who can take an entire month and devote it to hunting. I guess in fairness, you have to also add "Time" to the list, as well.
"Location" plays a big part, also, obviously.
It's not as simple as luck versus skill. There are other factors
hysical abilities, weapon, outside hunting pressure - just to name a few others.
All that said.... I know a skilled hunter the second I meet them.
