Does it matter if you are from Illinois?
I actually got some good money at one of these events turning in trash rifles. My Grandfather passed away and cleaning the barn found 5 old shotguns in horrendous shape. Maybe you could have pulled a couple parts off them, but they were just rusted, pitted, warped wood, sad sad shape.
Took them in to a county Sherriff office 5 counties away and got $250 on a debit card. No way those guns were anything close to that. Gave $125 to the wife, and spent mine on fishing gear and some truck parts. Made my day.
I am from Ohio, an open carry state.
