When it all comes right down to itThink about this.........idiot behind the wheel of a vehicle. I see them every day. A vehicle weighing in at two tons plus is more of a threat for me, and a driver on a cell phone compounds the problem. Then throw daylight or dark into the mix!Idiot with a gunWouldn't that be nice if it were an easy way to fix things. Just like curing a disease.......I think there are those that become immune to the cure.It looks like the gene pool needs a little chlorine.
