I'm not advertising here but I'm really excited about a book I got for Christmas: Common Nymphs of Eastern North America by Tzilkowski and Stauffer. If you're a nymph fisherman, want to be, or just want to know what all that stuff in the creek is, this is a great book. Great photography and great text. They do a great job of showing you the live nymph next to the tied fly. The pages are even waterproof so I can take it stream side. I was so excited I had to pull the waders on, run down to the creek, and cast a few Prince Nymphs. Great day!
