I recently had an incident that caused me to reconsider my views on safety. My wife and I were out for a quite evening of fishing on a local lake. Near the public beach is an area of scattered rock and grass, and we were throwing a few crankbaits and enjoying the evening. While drifting along, we thought we heard someone yelling, "help"! We looked around, saw nothing and continued fishing. We heard it again, and saw a head bopping up and down in the water, well away from the buoyed swimming area but inside the no boat zone. I quickly kicked the trolling on high, and my wife grabbed our throwable from the storage bin. I have the "minimum" legal requirements in my boat - a throw-able, and the required PFD's per person.
