So far, in my experience hunting. Animals are going to smell or hear you miles before they see you. If not wearing camo caused you to be unsuccessful, you weren't going to be successful in the first place.I've thought about this a lot lately, the older I get the lighter/more casual I dress or approach a hunt. Lot of money wasted. Some of my most successful hunts have been in jeans and a flannel. Same way they did it years ago. I think if I never hunted in camo again I wouldn't kill one less animal bowhunting or rifle hunting for instance. Ymmv.
Took my boss duck hunting last year he was all nervous cuz his camo didnt match. Told him dont worry the ducks dont care if the guy who shoots em matches.
