I knew one fellow who was studying to be a county extension agent, which always seemed to me to be a direct analog to the pursuit of a Ph.D in the liberal arts, except that one needed only a bachelor's, and getting a job was much easier. In both fields, one gets to pontificate mercilessly, and utilize theories that nobody has any idea if they really work, but in county extension work one gets as an added bonus to drive a pick-up truck from student to student. When I was in college, I would no more have dreamed of pursuing a degree in agriculture than I would have dreamed of becoming a beautician at the Ace School of Beauty and Nails, but hindsight has convinced me that those fellows were really on to something. The study of soils and plants and critters and agribusiness is a rich field unto itself. Of course, if I practiced what I preached, I'd go to my alma mater for an LLM in Agricultural Law, but I am much better at posting than at practicing. For that matter, if I could cut paper in a straight line, I think it would be fun to be a barber. I am very good at discussing politics, hunting dogs, get rich quick schemes like earthworm farms in the back of Field & Stream, and the Porter Waggoner show, which were the main qualifications when I was a kid for effective barberdom.
The agriculture department raised a lot of its own produce as an educational exercise. They had their own little store to which students could go to get reduced-priced items. Those of us who lived in dormitories had little need of "real" food, but some of my friends used to religiously get the cardboard box of milk. This box was shaped about three and a half feet long, and two feet high. It didn't have the conventional appurtenances of a milk carton, but instead had a little plastic tube in its side from which one siphoned the milk. Don't ask me why, but there is something immensely cool about siphoning one's milk from a drab cardboard box. Now I get my skim milk from a standard little plastic jug for my raisin bran, but I long once again for a "bulk food" box of milk, with a plastic tube for easy squirting.
I feel the hankering to study something lately. Maybe it's time to find some inexpensive distance learning program.
