I gave cave tours.  Why people wanted to go in caves... who's to say?  But if they'll pay me to take 'em, I'll take their money.  I've been down in those tunnels so many times, I don't need a light.  I know when to duck.  But you should hear them people complain.  What did they expect?  It's a cave.  Caves are dark.  It was the insurance companies that put me out of business.  Bloodsuckers!
