Louis is planning a fundraiser for a local charity. He wants to spread the word around the community to get as much support as possible. Which of the following would best help him publicize his event throughout the community?
A.) a letter written to the editor of the events section of the town newspaper
B.) a commercial broadcast hourly on the local radio station

I'm thinking A, no one really listens to radio stations and more people read up on newspapers. Not sure though.
