You could stay home and warm them in front of the fire like some of us poor saps have to do. Or, if you're lucky enough to be out fishing (as you apparently are), you might try a thin layer of vaseline, then surgical gloves (the good ones that are sized, not the cheap ones you buy by the boxful), then plain old cloth oxford gloves with the fingertips cut out. Of course you'll want to use nets to handle your bait, but with the vaseline and the gloves, even if you do have to reach into the water, your fingers will warm back up instead of staying frozen to the bone. Until, of course, you poke a hole in a glove with a hook.

Best of Luck on Your Float 'n' Fly Adventure!
