I tried some 20yr old power bait on trout last Sunday Didn't get out till close to two o'clock and never got a hit but it still smells and is soft enough to put on hook! I'm gonna have to try it on crappie just for the heck of it. Seems everything used to catch fish smells like fish,,,,,except for catfish if your using chicken breast soaked in kool aide and garlic! You could probably add chicken and beef liver to that too!
