Knee deep in a Montana trout stream I waited for the trout that I had been watching to show again; gently sipping in the occasional tiny hatching mayfly that slid gracefully across the slick surface on that perfect autumn morning. A gently breeze wafted through the streamside trees sending a shower of leaves cascading down like a golden waterfall. The trout rose again, pushing a barely perceptible circle of broken water away from the place where he sipped in another fly.
