Welcome to the boards dadgummit. It probably aint a good idea buzzing the brushpiles 3 or 4 times before you fish 'em though. If that dont run 'em off it will definitely give 'em lockjaw.Maybe using a depthfinder on front of the boat with a trolling motor? Maybe a GPS? (I even had a buddy years ago that found the brush piles using nothing but a splitshot on a rod and reel to locate the exact spots his brush was at. Again, welcome to crappie.com.
Health nuts are going to feel stupid someday, lying in hospitals dying of nothing.
