In case you missed it, this item was in the 25 Years Ago section of The Way We Were on this page last week:
Starting with the VCHS homecoming parade Friday, the city of Vandalia had new rules governing parades. Those rules stated that parade participants would no longer be able to throw candy or other give-away items, and that parade watchers would be required to stay on sidewalks.
That tells you how long crowd control has been an issue. In fact, it's continually gotten worse, especially in recent years.
