The key to efficient snowplowing...

The key to efficient snowplowing ... isn't finding the route for your snowplow that scrapes all the driveway/parking lot surface most efficiently.  In fact, that's almost irrelevant.  The key, my fellow snowplowers, is finding the route that most efficiently pushes all that snow to somewhere where you can pile it up.  The periphery of my driveway is roughly 50% places where I can't pile snow (because of trees, etc.), and 50% places where I can.  The entire trick to getting the snowplowing done quickly is to plot routes for the snow I scrape to those allowable depositories.  It took me a while to figure that out the first year I plowed snow up here.  Now it's second nature...
