It's a club, it stands for "head, heart, hands, and health" lol.
Here is the 4-H pledge:
I clear my
head for clearer thinking,
my
heart to greater loyalty,
my
hands to larger service,
my
health to better living,
for my club, my community, my country, and my world.
(Gosh I hate saying that, lol)
We meet every Monday night, there are thousands of these clubs, and they do everything from horseback riding to gun clubs, to sewing and cooking, or all of them combined!
I am in a purely dog club. We do basic obedience, showmanship, agility, therapy work etc.
