How to get dirt into every pore of your skin... the secret revealed!

I don't have pictures of this one, and keep forgetting to get some from Larkin. Larry orchestrated this one. A troop of Larry, Larkin, Ralph, Mary, and I drove down to Indiana, chasing the promise of a second location for an all-day cave tour. This tour was wetter and a bit more gruelling than Mammoth. There were places where exhaling seemed necessary to pass, and an icy river spanned the entire floor. Well worth the trip if you're interested in exploring, underground.
