You know what they say. (A bad day of fishing is better than a good day at work.) X-ray vision sure would come in handy. You would be able to see what the fish were biting on.
Some of the best trout fishing I've ever done was in the Snake River in Wyoming. The Cutthroat Trout were there for the taking, most weighing between 2 to 4 pounds. Their meat was pink and dipping it in butter, you thought you were eating lobster.
What a beautiful place!
