In this intimate class, Paul Aguilar, fly fishing guide with Silver Creek Outfitters and part of 5B Anglers, will answer a key question – which fly do I use? By analyzing an insect’s shape, participants will learn how to identify key parts and then practice tying flies for fishing. Hosted by Hailey Public Library on Thursday, February 27 from 5:30-7:30 PM at Town Center West, 116 S River. Free.
