That is the most absolutely brilliant idea I've ever heard to help get this situation under control. Totally feasible also. The technology exists already. One may argue that is wouldn't work on the oceans, but GPS technology is such that those areas could easily be "blacked out". People on lakes and rivers might be pissed, but again what is the cost of a life? Fantastic idea! Now, how can we get our legislators on board and get something worthwhile done?
