The Four Hs, if you wondered, stand for “Heart, Head, Hands, and Health.” The organization is sponsored by an extension of the USDA and was originally designed to strengthen the connection between public school and rural life. The Hs are taken from the 4H pledge:
I pledge
My head to clearer thinking,
My heart to greater loyalty,
My hands to larger service, and
My health to better living,
For my club, my community, my country, and my world.
You can learn more about 4-H programs here, or just enjoy the fair.
