Can I hop in here and give you my 2 cents...
Start looking for "hard bottoms" even if it is only a scratch. Ledges get hammered a lot and hard bottoms tend to get skipped over more often than not...
Even check the ledges that are only a foot high, they hold a lot of fish. If you are going to fish a ledge, you need to look at it from one end to the other. I look for cracks with hard red in them, that is good fish. Sometimes the fish are on top of the ledge and sometime they are on the deep side, Figuring that out will take time but after a while, it will come.
Another thing to remember is when you read their reports, you will see that they sometimes move a lot, no one spot will give you their results...
Call me if you would like to chat more about it.
