What did do as a kid to earn money ?

I lived right beside a golf-course, me and my buddy would go empty their garbage cans that was on every t-off of the beer and soda cans, and sell them for the aluminum.

And we would empty the water traps of any golf balls, wash them in the ball washer on the first tee-off and sell them to the club house. They would then re-sell them as used balls.

Endless supply of cash during the summer, this was all after the golf course closed down for the day.
