Mousing for big browns is arguably one of the best ways to catch 20 inch fish. I'll admit I was pretty intimidated by it at first. Fishing in the dark, with no lights, with a fly rod, on a river??? I thought "No thanks I am all set." However when you get an invite from someone like Brian Kozminski or "Koz" as he is affectionately known, you don't say no. Brian is one of the most knowledgeable trout anglers out there. He has been guiding for many years, and you can tell he truly enjoys teaching others.
