Host an adult spelling-bee competition to help raise money for your cause. Much like a walk-a-thon, participants are called upon to gather donations from their support network, based on the number of words they spell correctly, as opposed to donating so much money for each mile walked. Conduct the event on a weekend or evening so kids can attend and see adults sweating in the spotlight.
Tip: Pull in community leaders to make things more interesting. They will also lend wonderful support to the event.
