I had a guy ask me the other day about what I do to keep ice from forming in the guides of my fly rod. In fact, I think we've talked about that here now and then. For the record, I squirt my guides with Pam cooking spray before I fish, and that helps for about an hour, depending on how cold it is. But the real cure for not having ice form in your guides? DON'T FISH when it's below 32 degrees Fahrenheit.
