Local History tidbit

I was reading about Irondale's history and found it interesting that our town is an unincorporated community and census-designated place in Clayton County, which got me thinking about how our community has developed over time. Given that our homes have a median value lower than the state and national averages, I wonder what other lesser-known facts about Irondale's history might be out there - do you have a favorite piece of local history or trivia to share?
