I remember as a child he had a gang truck.
One of the hired hands from the university (future engineers) had attached a bumper sticker about being a piano player.
Dad at the end of Summer would give all the young college kids a coffee mug that said “I'm so smart I make myself sick”.
Nothing like running a long handled Mexican backhoe squaring up ditches to help make a young kid decide to stay in college and get an education.
Good story. Years ago I remember high school boys doing roofing jobs in the summer. They were paid more than anyone else, got a great tan, built muscles, and swore they would never do that job again, ever! ;^)
