to run nimbly and usually playfully about
You may be taking a long stride with one foot while executing a stutter step with the other, all done automatically, unthinkingly, just doing it. You skip joyfully downhill in an exhilarating rush, much more fun than picking your way gingerly down. And, in my opinion, doing it just as safely, while having a blast!
One of my best mental pictures is of my buddy Dave C from Shippensburg as we ran the Appalachian Trail north near Pine Grove Furnace State Park. There was a rock-filled downhill, big rocks, not little rollers, and Dave without thinking took off hard and fast down the trail. I watched amazed from above as he literally scampered, loving the run, safely and sure-footedly picking out the route. I can see that image as clearly as when he did it some 12+ years ago, in a move that I call "Scampering 101."
He set the bar high and every single time I've done it since I've been rewarded with childlike joy and exuberance.
