Fishing drops, ledges etc. is without a doubt something that MUST be done with patience. If you want to learn how to fish these types of structure I HIGHLY recommend a trip with Dave Stewart. Fishing drops, and ledges is without a doubt one of my favorite types of fishing. One thing that I have learned about this type of fishing is that it REALLY takes a lot of time to learn. One thing I can tell you about some of my best drops, ledges I have fished is that it took me a lot of time to figure these spots out. I have found several drops that I have sat on for 1-2 hours before catching a fish. Once you catch that first fish, you get clued in and really do some damage. You've got to learn how to look at the water and visualize how the drops lies before your going to do much really. Visualization plays a huge role in this because after you learn that, you know where your bait is on the structure at all times and then can almost duplicate that on other drops. After you learn how the drop lies you can really narrow your time down on fishing other drops and ledges.
