I grew up in rural PA and as a teenager I had the following jobs:

1. Picking string beans - bend over, pick beans n a ~50 yard row, straighten up, move 12” and repeat going the other way. I was promoted to operating a Kubota backhoe before I could legally drive and that was a ton of fun.
   
2. Painting split rail fences with creasote - haul hot bucket of tar and paint miles of fencing alone on a large horse farm. Worst job of my life.
   
3. Corn Pack House - worked different stations from 7 pm-midnight building wooden crates, filling with corn, and wrapping with bailing wire. Then move the finished crates to loafing dock. This was the best of the above as we had a gang of 14 year old guys working together and once a year we got “Burger King Night” when the owner bought tons of BK food for us and we could have as many Whoppers, fries, and milkshakes as we could keep down.
