My definition of "over the hill" is when I can no longer go up and down said hill. In other words, when I'm no longer able to put one foot in front of the other, or I can't see well enough to drive to the trailhead....

On the other hand, I'll no doubt find something else to do then, until my time comes!
May your trails be crooked, winding, lonesome, dangerous, leading to the most amazing view--E. Abbey
