A visit to the Michigan State University horse barn, on their breeding farm, where they breed champion Arabians, as well as Belgians, Percherons, and Quarter Horses.
The foals are in the barn, or outside in pastures, and they're curious, and well-tended by their mothers. The mares are bred yearly, according to the staff, and are clearly well cared for, and friendly, letting you touch their babies so long as you get their approval first. If you are there at the right time of the year, you can see day-old horses, still wobbly on their feet.
I like to see things, and so I wander - and I wandered into one of the breeding buildings, complete with a "false mare", used for collecting semen from the stallions.
MSU has many farming and animal-related classes, and a variety of separate farms on their campus, all of which are open to the public daily. Check them out if you're in the area!
