So I had the privilege of taking around a nice, smart group of kids. They asked really good questions, were eager to learn, and liked climbing on the tractors, of course.
I ordered some tour swag from UDIM (which every Michigan dairy farmer gives money to), and the kids liked their milk-themed coloring book, pencils, crayons, food clips, etc.
What they also loved was answering questions for a Gogurt! I said I'd ask a question and the person who answered correctly would get a Gogurt. The boy who answered first said, "How many can I get?!" (I'd only brought a few extras, so I couldn't give him more. But I liked the enthusiasm.)
They also got to see a REAL LIVE FARMERS doing REAL LIVE WORK. Which is exactly how I introduced Kris and my dad.
But really, the Gogurt generated the most excitement. Even tractors can't compete with free food.
