When I was a 11 years old, I was fortunate and Santa gave me a (used of course) Sheridan Blue Streak 5mm pump up pellet rifle. We were living in a rental house in a rural area and I got to know the neighboring farmer. He had a building where he stored seed corn. It was rat/mice infested. He offered me a penny for a mouse and a nickle for every 2 rats. I earned enough money that fall to purchase a brand new Zebco model 22 fishing reel. I shot hundreds of those critters. I could hit a penny at 25 feet every time. Unfortunately, we moved to town and I lost my job, so to speak.
