Older dog learns a few new tricks
In 1979 I had a crew chief for about 1 year who had a physics degree from MIT. He was a very good surveyor and could tolerate the weather, wear muddy boots and dig holes with the best of them.
There is absolutely nothing wrong with obtaining a higher education. Do what you want to do no matter what that education happened to involve.
About 30 years ago I stopped in at the local livestock feed store/mill one Saturday morning to shoot the breeze with the group I could tell were gathered there for basically the same reason. A nice collection of old farm trucks and second hand vehicles along the street. Inside there were four engineering graduates, two teachers with masters degrees, a West Point graduate turned DVM (veterinarian for the acronym challenged readers), a school principal with an Education Specialist degree, one graduate in Agricultural Education (vo-ag teacher) who could make more money as owner/operator of a fleet of semis and one young fellow with a degree in Economics. Most of those present have been getting together for major holidays since they were kids or since they married into the family. The DVM now is owner/operator of a business specializing in artificial breeding and cloning of premier livestock for customers across the North American continent.
