It is the teen version of Kiwanis club. In our community kind of important as Kiwanis puts on our 4th of July fireworks, carnival, a big deal parade, summer concerts etc…and Kiwanis a ton of service work beyond that, offers scholarships and so on.
D joined Key Club, probably, because most of her friends did too. It’s just something a certain kind of kid in our area does (my S did not, he’s not that kind of kid). Also, we have service hour requirements to graduate and Key offers them.
In her HS Key puts on a battle of the bands to benefit bone marrow donations/awareness, runs “market day” to raise money for various charities, and helps out at a lot of community events.
