Connie and Bunky Boger pride themselves on their ability to teach about agriculture with their traveling petting farm.
The Hennepin County Fair, Minnesota's first county fair of the summer, was fertile ground for their mission last week.
"This is where your milk comes from. It doesn't come from Wal-Mart," Connie explained as she helped 3 1/2-year-old Pryce Toyne milk a cow the "old-fashioned way."
Connie explained to a small crowd of eager children and their parents that a cow must have a baby before she can give milk; that a cow's milk is warm because cows are mammals; and that nowadays most cows are milked with a vacuum pump.
Every child was given a chance to milk Sally, the gentle Holstein that was part of the educational exhibit.
"Our purpose is to explain to people about agriculture," Connie said. "You have got to educate them without them knowing you're educating them."
The Hennepin County Fair, one of the oldest county fairs in the state, has been around for more than a century and has been based at Corcoran Lion's Park for the past 26 years.
Five years ago, the directors stopped bringing in exotic animals to focus on their goal of educating people about life on the farm.
