Anyone ever heard of a doodle line? Years ago when I was a boy I remember seeing old timers rig these lines. The line consisted of a main line that had a looped knot about every 4 to 6 ins. making about a 6 in. drop. Hooks had the doubled line of loop run through the eye of the hook and then around the bend and then pulled tight. You had to put the line through the eye from the right direction so if drug across your hand the point of the hook would dig in. If you run your line through from wrong direction the hook will roll on its side and slide by not hooking anything. These lines were soaked in motor oil mixed with anise oil. They were put out like a trotline with no bait. The catfish were attracted to the smell and would rub the line foul hooking themselves. I have never fished a doodle line but heard about them a lot when I was a kid.
