The 2016 Tonasket, Washington, population is 1,016. There are 1,265 people per square mile (population density).
One of these is the Side Marker Light, which indicates a vehicle's presence and its dimensions. But even if you don't drive a truck or a trailer, installing this type of light is a great idea since it makes driving in poor visibility conditions so much safer.
Marker buoys are a necessary part of structure fishing IMO, even with good electronics. Like Fluke, in shallower water I try to use the trolling motor. With buoys in position I can focus on presentation. I don't leave home without them.
