Darrell Pendergrass describes fly fishing for trout at night in his article "Fishing blindly for trout with the eternal optimist" via the Superior Telegram:
"Simply put, almost blindly a cast is made, a fly drifts casually for a bit, and then the soft sound of a trout coming to the surface is heard. You need only to lift your rod and line from the water to know that you’ve succeeded in hooking a fish. It’s calm. It’s quiet. It’s perfect. And I believe the term ‘blind luck’ was actually coined by Scottish fly fisherman back in the nineteenth century."
