If you think one person can't make a difference, tell it to Joel Davis. Born with scoliosis and other physical challenges, grassroots activism gave Joel a new lease on life. Organizing tea parties, walking door-to-door and hammering yard signs, and testifying in favor of medical marijuana was just the beginning. Joel took the tools he learned as a citizen activist back to his hometown and began applying new skills to help fix problems in his local community. Using Facebook and knocking on every door in his precinct, he won a seat on the city council. He is now the new mayor of Paden City. The tools he used to succeed in politics are now the means of growing community involvement in local challenges, and creating new transparency in government service. Still think one person can't make a difference? Ask Joel how to get it done.
