Our church has taken to advertising on local billboards and it has been quite effective! Here is the most recent - about our Easter events at the church. The Contemporary Christian music group "Avalon" will be there. They are terrific, so if you're local - STOP BY! If you have kids, they will simply LOVE the "Kidstuff" program we have on Sunday mornings.
The church photo is one I took that the church uses pretty extensively for advertising and such.
