Carp fishing is where I learned about drag settings. My grandfather used to take us and set us up for carp while he fished for rock bass. Being a smart a$$ 10yr old, I figured why should I take forever to land these fish and let them peel off drag. All I need to do is tighten the drag down all the way and land them in no time.
First hookup after my genius idea and >PING< goes the line. Cue lightbulb illuminating over my head.
