Or the wannabes with their fog/driving lights on?? Always out of adjustment. Public transportation was made for these asshats.
Tug boats--- I am driving on an interstate and the Missouri River parallels parts of the interstate. I have this blinding light coming through the windshield but there isn't a vehicle in sight----- it was a tug boat on the river.
Lights on the water. Fishing G'Ville I noticed most boats had a light on each side screwed to the rubrail. When I inquired about them a friend ( and a guide) said "At night on G'Ville if you don't run lights, you will hit something that will sink your boat'.
Speed limits at night on a lot of lakes is 35 mph.
