The dogs know the way back home.  The race is done, you're exhausted and your sense of direction is gone.  Three trees past the last snow drift and everything looks the same.  Hold onto your sled and give the lead dog his head.  The dogs sense magnetic fields, all animals do.  Surrender and trust four-legged intelligence.  If all your life is one long modulation then a shift into triple rhythm doesn't change your tune.  You fail forward faster.  Let go and let the dogs find the way.
