What did do as a kid to earn money ?
I mowed lawns for like 2 bucks each, pushing dad's lawnmower around the subdivision in the SW Chi Burbs. Also some occasional snow shoveling ('67 was a *****).
Moved back to Chi. I did paper delivery b-4 school for almost 3 years. Never will forget. Over a 100 Sun Times and Tribs (81 on Sundays). They cost customers $1.09 a week for either. Did the collecting as well. Tips were better than the pay. Great money for a kid back then.
Bikes were like this one (picture from the net). Sunday also required a bag in addition as papers with the "stuffs" wouldn't all fit in the basket.
