Urban fly fishing is fun and presents some challenges—like bystanders getting in the way of back casts and sometimes fishing from a location high above the water. And it's essential to know how to fish around bridges as these are sometimes the best habitat for urban fish. Marc Fryt [38:33], whose new book The Guide to Urban Fly Fishing is a treasure trove of tips for exploring this exciting world.

In the Fly Box this week we have some interesting questions and tips, including:

Is there a place I can explore saltwater fly fishing on foot without a guide? I can't afford one right now. When storing fly tying materials, what should I do to prevent damage? Will excessive heat or cold in a garage or attic affect them? Do you have any tips for catching my first grayling in a lake? How should I set the drag on my reel? Are Orvis' mid-priced rods like the new Recons just blanks from older versions of premium rods or are they completely new designs? A listener reports that he uses a light for trout fishing at night and it does not spook the fish. Why do my loop knots keep breaking when streamer fishing? Why do you cast with your right hand and then reel with the same hand? What do you think of competition jig hooks that ride upside-down? I have a Clearwater 10-foot 4-weight that I use for dry-fly fishing and want to try Euro nymphing with it. Should I get a new reel or spool with a separate line or just switch my leader?
