While working at a marina in college, I pulled out dead minnows from our live tanks and threw them off the dock every day. Usually, I'd watch the minnows float away to see carp and crappies come up to snatch an easy meal. One slow morning, a big fish appeared out of nowhere, grabbed a minnow, and was gone in a flash. I ran up to the marina to grab a hook and line. I dangled another dead minnow just off the dock and before I knew it, my line snapped by that same lightning-fast strike.
