My grandfather used to keep them in his bass boat. That and Beenie Weenies. Got to a point where the labels were gone or just faded away. So you had to open the can to find out what you were getting.
When fishing for catfish if my Dad got hungry he'd spear a chicken liver with his pocket knife then cook it over his Zippo lighter. Once I tried one I could have finished the livers and damn the fish!
