About 100 years ago, my Grandfather earned his living for several years as a professional flyfisher. He would fish the trout streams of Colorado with his flyrod, & sell the fish to the mining & logging camps. Since it was his livelihood, Grandpa's primary concern was catching as many large fish as possible, & he utilized numerous techniques to fill his fish sack. One of the most effective techniques Grandpa used was the dropper fly, which consistently produced more and larger fish. The dropper fly is still an amazingly effective technique today.
