cave training in caves

[Dave Lizdas]

Fin marks and hand prints on the floor remind you that your favorite cave has been visited by impatient or careless divers lacking basic control. You took it seriously enough to attain a certain level of perfection and respect, and yet, this fool just jumps in. But these scars are asthetic marks only. Many will vanish after a few decades.

But I'm wondering how many of these hand prints and rock scars our kids will notice swimmin around in green tea viz, considering the excess nitrates dumped on lawns and farms many miles away, parking lot runoff, etc etc...

Good point. To borrow from the famous quote by Chiang Kai-shek, handprints are a disease of the skin, pollution is a disease of the heart.
