Don't Catch a Falling Knife
Well, this isn't that Vancouver bridge. (See Magpie pins) Why was it built? What might we find at the far end of our tree bridge? Elves enticing us to dance about a midnight fire? A really great picnic spot? Teensy furious faeries firing pin-sized arrows at us giants, who stomped their picnic site flat? Thunderous thuds! A dark shoe-shaped cloud plunging toward us! Splat!
