I have been fortunate enough to get my hands on a good bit of scrap pvc pipe. I have followed the lead of some designs on here. I have dug some holes in the ground the same diameter of a five gallon bucket and placed the 7 or 8 foot sections of pipe in there and filled it with concrete. I will be putting them in Guntersville, a TVA lake I guess. I am mainly concentrating on deeper places to fish in the summer and winter, edges of channels, etc. I would also like to put some in the transition areas from deep to shallow cover. I have a few areas I hit now that have this type of cover, but I think you can never have enough go to places when they get pressured.
