Many traditions exist in traditional fly fishing. There are some that are shared by many, such as gear that is universally used , and others that are only done by individuals . For example, my father always selected his three length rod and individually tested each eyelet before threading the pole with his line, this constituted a tradition (Sims 2011). With all of these traditions and rituals, they circulate around two principles. The first is the idea of luck,  luck created by the mental shortcuts in traditions (Powell 2017). Fishermen need luck like fish need water. As pointed out by Kendall Powell in the phenomenal nature article, behavior a lookout for luck, these rituals help condense a belief that one will be successful. Popular traditions among traditional fly fisherman are showing up before the sun rises, leaving electronics behind to limit distractions, and leaving your neighbors in peace. Other traditions and principles circulate around the idea of sustainability. Examples of sustainability is catch and release , leaving the environment cleaner than when you found it, and not disturbing wildlife as much as possible.
