I remember as a kid, dad would take me perch fishing off the rocks. We used a trolley line. The way this works is you throw a heavy anchor as far out as you can. Put up a long pole, than tighten up the line and attach as high on the pole as you could reach. To this you attach a trolley which was a weighted gizmo with 2 wheels that snapped onto the line. This was attached to a old bait caster black line and lowered down the anchored rope. This had a series or red beads and snelled hooks on it appx. 1 or 2 feet apart. It had about 8 hooks if I remember right. You lowered it down as close to the bottom as you could and then just hold the line to the reel and fish as you would tight line. It was quite unique cause I remember dad getting a bite, setting the hook, waiting, waiting, another bite, set the hook and continue. After a few fish he would reel in the line and take off the fish. I am telling this story cause I found the set up in the garage after a big clean up. Was wondering if anyone else had ever fished with one of these contraptions. Brings back memories.
