I normally take my wife to work and pick her up, she works the afternoon shift. Since it has gotten nicer I have been leaving early and going down by the river, near the mouth of the lake. I sit and listen to the Redwings, Pistons, or Tiger games while fishing for Pickerel. I see a lot of lake freightors pass by and often I will see someone on deck, or looking out an open hatch or door. When I do I will take one of my lights, usually my Inova T1 or Streamlight Stylus Pro and flash them a few times. It is impressive how many carry a flashlight, it seems that about 95% will flash a light back within a couple of seconds.
