anyone who would not have nav lights on is not only a danger to themselves but also me and everyone else. you would have to have some sort of chemical imbalance of the brain to even think about not running your nav lights at night. but nothing suprises me anymore. soon you will hear about the people in kayaks at barren river getting ran over. 3 of them were out in the dark with no lights as a tournament was ending last year and almost got nailed by the boat that was running in front of me. luckily i seen him cut hard left at the hogs back and thought it was odd to do so, so i let off and followed his line and then seen why he had done so. dont let your last fishing trip be due to something avoidable.
