Watch the news! Check out the community blogs! Look at the local newspaper!
Find out the "news" for your community and plan programming for those topics. I often hear that people do not attend adult programming, and honestly, they don't - unless the topic is very important in their life.
One idea that came to my mind this morning as I read the newspaper, yes actually a print newspaper, was "staging your home to sell." The real estate market is tough and many in your area are probably trying to sell their home. There is a great article about staging that could be used to create the program or contact a local agent and see if they will present for you.
