I drove by a church the other day on 3 mile rd. that was advertising a FREE party that was happening on the 18th. What caught my eye was that they advertised that there would be inflatables there. The church is called Anchor Baptist church and it's happening from 1-3pm. They also had cotton candy and popcorn on their sign but I'm not sure if that's FREE also.
