Scott Sadil [41:39], author and Fly Fishing Editor of Gray’s Sporting Journal, is a pioneer in fishing the surf in Baja, and in his many years of experience he’s learned a ton of valuable tips. Even if you never plan on fishing Baja, you’ll find his advice helpful for finding fish along a wide beach, choosing which flies and tackle to use, and learning new techniques for moving the fly.   In the Fly Box this week, we have some fascinating questions from listeners, including: I am having trouble casting a size 6 fly with lead eyes on my 5 weight. What can I do to correct this? I am struggling with my distance casting. Any tips for helping with this, and for fishing large tailwaters? When I hook panfish and bass along a shoreline, they always head for shore yet carp always swim to deep water. Why? My Royal Wulffs don't float properly when I drop them in a glass of water. What can I do to help? What kind of flies and colors do you suggest for fishing the surf in Costa Rica? How should I dispose of old waders that leak? Is there one rod I can use for surf fishing, largemouth bass, and streamers for trout? If you float a river in a canoe of kayak by yourself, how do you get back upstream at the end of the day?  Should I use a 7-weight or 8-weight rod for throwing big streamers for trout? How should I fish freshwater rivers that are tidal for bass and pike? And how do I get wire onto the end of my leader for the pike? Why do people use a Bimini Twist? I would think it just pushes the weak spot in a leader further back.  Is bug spray harmful to fish? If I am hiking into high alpine lakes, should I hike in my wading shoes?
