There is a very popular Canadian fly fishing show called The New Fly Fisher. Fortunately for us, they also have an online "ezine" related to the show and it is free. There are some great fly recipes, articles and photos. Plus, a bunch of videos. More than your usual online magazine fare.
I particularly liked the article "Smallmouth On The Hex". Here in central Indiana we mostly hear about trout and hex flies. There is also a nice article on Freshwater Drum. Now how many times do you see someone write a fly fishing article in Fly Fisherman on freshwater Drum? NOT!!
Check out the magazine. There are 195 pages of fly fishing goodness. Then subscribe and enjoy each issue.
