Shortly after moving to Colorado, wintertime, the weather was mild and a local river had some open water around the ice.
A friend told me about dropping a fly onto the ice, cross stream, and letting it plop into the open water. Hungry fish hiding under the ice would surely grab the bait.
So I did, and they did, and then I discovered that a fly, with any water on it at all, will hit the ice and freeze to it. So I caught one nice rainbow trout per fly, and the ice shelf started to look furry with hackle. Fun but expensive.
