We used to catch Bluegills and hook one of their eye balls on the hook then keep fishing. I still collect all of my own bait. My neighbors asked shortly after I moved in why I was out in the rain in the middle of the night on my hands and knees in the garden with a light on my head, all I had to say was I hate buying night crawlers!
Frogs, minnows, grasshoppers, chubs I still feel like a kid out collecting them!
