One day, he was walking beside a stream in which rainbow trout were plentiful. He watched a lady reel one in but toss it back and wanted to know why. She told him that game wardens do not allow trout as small as the one she tossed back to be kept and complained that she needed a better plug that would attract larger trout.
Peter decided to solve the woman’s problem. He read about rainbow trout and learned that they feed on insects that fall or land on the stream’s surface, but the largest rainbows rarely rose to the surface and preferred to spend their time in the cooler, deeper water. He also learned that loud colors attract rainbows. With these facts in mind, he turned to what he did best: solving problems. First, he carved a fat minnow from persimmon wood, which is best for plugs.
But a problem arose. Like all woods, persimmon floats and Peter wanted the plug to hover near the bottom to attract the biggest trout. So, he designed a long, spoon-shaped lip on the minnow, which would cause the plug to race downward when fishermen cranked their reels. Then, he attached two barbed hooks, one in front and the other in back. Both were connected to the minnow’s belly and hidden in rubber strips that resembled grass. Finally, he chose a loud, fluorescent pink to color the plug.
Another problem arose. Peter had no fishing tackle. As always, a solution popped into his head. With the new plug in hand, he returned to the stream, and as luck would have it, he spotted the same lady fishing for trout in the same spot.
