Caroline Hambuchen and Mandy Shum were among the Interact Club members who sold Valentines to fellow students Monday and Tuesday. The paper hearts had messages and blow pops or dum dums attached to them for 25 cents each. They'll be distributed to the recipients on Valentine's Day. The money raised helps support polio eradication around the world, which is a major project of Rotary International. Rotary is the sponsoring organization of Interact Club.
