Until last year, I had a very small boat fishing out of Holland and tended to stay in closer than other boats most of the time. I have read that book several times and agree, there is not much structure around here that is obvious. However, I noticed when you are running out of Holland (especially at a slower speed) it stays approx. 50feet for a very long time. I have fished right where it starts to gradually drop off from that depth and done well a number of times while everyone else is out much deeper. I have also talked to several others over the last few years who have "hot spots" relating to a flat, a slight drop, or rise, etc... Anyway, from what I remember about the book the structure he talks about is very subtle. I am not sure I have ever really had a graph good enough to keep track of this, but have one picked out & I am hoping arrives before spring:D Good Luck!
