I'm 35, I made my 48 year old cousin go back up to the woods and clean his litter pile up one time. He was "teaching" his son how to hunt. I stumble across his spot while still hunting and it's littered with Starburst wrappers, coke bottles, and and plastic wrap.
He actually got huffy about it so I didn't hold back a single thought I had about it, or him. We haven't seen him since, lol.
I don't care who you are, if you're in my presence you are going to respect Mother Nature or I am going to call you out.
