The kids and I recently took a field trip to the Olentangy Caverns in Delaware. For those readers in the vicinity or with a love of history and Indian lore, it's worth a look. The caverns range from 75-105 feet underground and were used by local Indians as a hideout. There's even a "lover's bench". Legend has it that a young female would lure her perspective beau to the tunnel near it, whack him on the head, the drag him over to the bench to nurse him back to health and in doing so, ensuring his undying affection. Nothing like putting the fear of a clubbing into a man to make him commit!!
