The Duck Truck AC has a GPS (Guiding Poultry System). Anytime I want to go somewhere, I just whisper my desired location to the duck and then go sit in the truck. Next thing you know, the truck is where I want to be. It is a pretty simple system, at least for the user. I don't know how hard it is for he duck. Thomas Leech discovered the duck at a yard sale. Apparently, nobody knew what it is for. So far I have not wanted to go to the moon or the bottom of the ocean. Part of the key is that the Duck Truck AC is blue. Also, the groove in the hood is the wake from the swimming duck. Just remember, if people spent more time thinking about ducks, they'd spend less time thinking about other things.
