Which way do I go?

Emerging from a high mountain trail choked with aspen trees, I stared at a wooden post, weathered gray from years of punishment being staked out in the inhospitable environment.  Rusty nails had one little wooden sign with an arrow whittled in it pointing right while another similar sign had an arrow pointing left.  The faded acronyms on each were absolutely meaningless, so I went left.
