Dangerous Upstreams

I sympathize with Marsha's apprehension. Really, I do. It's in her nature to be cautious; she's a "Hophare" at heart — always a mere breath away from skittering off, dashing to safety and comfort. Well, regarding animals, I'm more of a Whitewing Vulture... I'm bound to the skies! It's my calling to glide above these freezing valleys! How can Marsha not feel intrigued by the upstreams outside our cabin? By the landing site just beyond the winds? Just how high up would they take me, I wonder? Perhaps far enough to reach the giant skeleton by the ridge? ...How steep would the fall be, dared I make a mistake? Alas, there's no point in pondering it. I don't want to break my little snow rabbit's heart. Or my bones.
