I reuse if they’ll stay in place. If they’re torn, they go in the trash. I don’t ever throw the old ones in the lake....heard somewhere if a fish, turtle, or bird eat it, they can’t pass it and they die. I usually drop em in an empty bottle or can.
A funny thing happened one time when my friend P.R. took my dad fishing. P.R. will use 10 different colors during an outing and when he’s done with it, he pitches it in the bottom of the boat. They found a honey hole one time and Dad went to tearing ole P.R. up! He asked Dad what color he was using and Dad said “I don’t know.....something I picked up out of the bottom of your boat!” Just whipped the man’s butt in his own boat with his own lure.....yep, that’s my Pop!
