Galloping on a horse down a rain forest trail, a blur of lush greenery rushed by. I could smell the leather of the saddle, feel the mahogany brown animal breathing hard beneath me. Matching the rhythm of his body with my own, I focused on the pounding of his hooves and the hushing sound of a small waterfall in the distance. My friend Ellie gave me a bright smile from her own horse. And then, and then! We slowed to watch the flutter of blue in the leaves. One, two, then a whole cluster of brilliant blue Morpho butterflies filtered up through the leaves and branches, each one like a dream that was all the more precious because it could not be captured and held.
