Dad bought the place in 1948 (140 acres for $4,500- those were the days!), and by 1951 he was milking "Grade A". We struggled along milking 35-40 cows until '61, when he sold the cows (but kept the farm). I got into FFA in high school ('62), and was really into farming. When I was a senior ('66), dad and I were discussing what we'd need to do to put in an elevated milking parlor and get back into the business. Mom overheard us, and said "We tried milking before, and it didn't work out. You might as well forget it, not going to do it again, son is going to college, and that's that". Dad didn't protest much, I think he was getting used to having some money to play with for a change. Wasn't much I could do without him backing me.
It was probably the best thing that ever happened to me- I got into part-time farming (beef) after I got married, and about 10 years of that was enough- to be honest, I really didn't take to physical labor all that much. If I had gone into diary, it would have been a disaster. Fast forward, had a good career and am now happily retired, and don't regret never farming full time.
