When I was glued to my TV set last year watching the rescue of those soccer boys trapped in a cave in Thailand, I thought about times I had been in caves. Most of those experiences were in Tennessee. Caves in Tennessee are fascinating. One of my encounters was in a primitive cave near South Pittsburgh. Usually a primitive cave is one that is undeveloped, with no pathways, no paid guides, and no admission fees. Those types of caves are on private property. Of course, all of the well-known caves were once primitive, until someone saw the opportunity to make a little money.
