Climb into a pair of waders and pretend you’re Tom Skerritt (or, sure, Brad Pitt) in A River Runs Through It. Fly Fishing 101 starts with rigging and tying lessons at the Orvis store in midtown, then the group walks two blocks over to Bryant Park, where there’s enough space to learn the fine art of casting. Fly Fishing 201 kicks it up a notch: Participants meet at the Harlem Meer in the northwest corner of Central Park, tie their flies and cast into the lake. According to Orvis New York’s fly-fishing manager, Rob Ceccarini, you’re pretty much guaranteed to catch something—just make sure you return whatever you haul out. Equipment is provided for both classes (registration is required), but if you want to invest in your own gear, you’ll get an in-store discount plus free membership to the Federation of Fly Fishers (fedflyfishers.org) as well as conservation group Trout Unlimited (tu.org).
