Carp fishermen (I know it's a flyfishing site but...) use remote control boats to cruise across a lake to deposit groundbait in exactly the place where it is needed.
What about a remote control Helicopter that you could attach a fly line to that would fly over a good distance to where the trout are rising and place a fly just right?
or drop a few insects on the first approach to get the trout excited before the actual fly is used!
You could of course have a larger variety and attach a hand-grenade but that wouldn't be sporting would it!? Could I get a restaurant interested?
......just a thought.
Have you any wacky ideas for improving your chances of catching?
