Most anglers have favorite "honey holes" they like to fish. Over my years of fishing, I have accumulated a collection of latitude and longitude coordinates of ledges that have proven productive. Last winter, I plotted the numbers on graph paper so that I could know, at a glance, where each ledge was located in respect to the others. That way, I could know the distance and heading to find them. I did the original plotting on large graph paper, which was too big and flimsy to take on the boat, so I brought it to the local copy shop and had them reduce it to 11" by 17" and laminate it. The resulting map allows me to troll easily from one ledge to another, covering the entire area. I always keep a chart of the area handy for navigation purposes, but my laminated graph helps me cut to the chase.
