What did do as a kid to earn money ?

You asked,, so I use to trap rats in a small game spring trap by their leg.
I caught many in the tomato patch next to a old garage were the rats lived underneath it.....I had a fool proof bait that rats could not resist.... My grandfather gave me a nickel for every rat I caught and disposed of.
Later on I mowed lawns, delivered papers, stripped stolen cars in the woods for radiators, batteries or other parts but never made money on that venture and finally at about 16 I got a good job pumping gas which I did until after I graduated HS and went to work in the power house full time
