For me, it started with "Self Defence", just two years ago. Then, while practicing shooting (so I could actually be effective in Self Defence), I discovered reason #2, shooting is fun!
I'm not a hunter, but several of my family are. While my brother has gotten deer with Bow and Arrow, fire arms are the way to go; Pistols, Black Powder, Shot Guns, and Rifles.
Exercising my 2nd amendment rights. keeping it relevant, is also important.
