Ode to a snowplow driver

For as much as I've been complaining about the weather lately, if it weren't for these guys...I'd be going NOWHERE! Have you ever seen the snowplow drivers in a tiered line (five or six trucks!) one behind the other plowing the entire 4-lane highway? It's quite impressive. For all those plow drivers out there - THANK YOU! If I have to go to work in a blizzard (darn you school teachers!!) at least the roads have been cleared (sort of).
