DIY learning to hunt it quite simple.
Have someone hide a contact lens somewhere in the back yard or city park. Go look for it. Multiple unsuccessful trips may be necessary. Total effort may be unsuccessful.
Armed with that experience, then:
Dress in camo and do it again. Again you'll be unsuccessful.
Then:
Pack for a 5 day trip.
Drive 300 Miles
Dress in camo
Carry a day pack, rifle, binos, crunchy snacks and water
Walk around in the mountains, woods etc looking for a contact lens
You are now hunting.
If you see a furry animal. . . shoot it. You are now a successful hunter.
If you shoot nothing, you have learned a ton and can build upon the experience.
Then: repeat this process many times.
You are now an experienced hunter.
