Fly-fishing is like raising children: both require patience, superior breath-holding skills, and a pocketful of flies to entice cooperation. Find renewed empathy for paternal units with today's Groupon: for $75, you get a one-day introduction-to-fly-fishing class at Silver Creek Outfitters in Ketchum, Idaho (a $150 value). This class is scheduled every Saturday until August 27, with additional dates available as needed. Each participant is required to acquire a one-day Idaho fishing license.

An oft-lauded tackle shop and outdoor store, Silver Creek Outfitters outfits fly-fishers with gear from R.L. Winston Rod Co., Sage, Simms, and more and instructs eager beginners in the art of luring underwater prey with regular classes. During its one-day introductory outing, a professional guide certified by the Federation of Fly Fishers presents a hands-on overview of fly-fishing’s basic elements, including equipment selection, casting, knot tying, and trout grammar. Silver Creek supplies the waterproof waders and boots, lunch for participants, and rods and reels for those who haven’t yet carved their own. Greenhorns will spread out along the water and earn their angling stripes by flicking out the line and pulling in plump rainbow trout, vegetarian piranhas, and the many other fish that commute to work through the local waterways.
