When I was in high school a friend of mine lived on a dairy farm. I have washed utters, connected the cows to the milking machine and cleaned up after the cows. The cows had to be milked before we went out at night. My dad worked for Wilson Dairy in Detroit. He was in sales and had 7.11's and Quick Pic stores in Detroit as customers. We had two commercial freezers at home and he brought home all the out of date ice cream. We would have 20 or 30 half gallons of ice cream in them almost all the time. During the summer, spring break and the holidays I worked there too. This was in the middle 70's. Driving into Detroit to work was always dangerous.
