He is an avid fly fisherman and often fishes in Montana. On the rewards of this hobby, Winkler said, "The repetition of it, the sound of the water, I find it to be totally draining. Anything that bothers you is completely washed from your body. I see fly-fishing as a washing machine for your brain. My technique is still ugly as sin. But somehow I get the fish. [...] I have never eaten a trout in a restaurant, let alone take it out of the river."
