Good point, serpent. Whether Monument or Park, so many things have changed in terms of what you can and cannot do. They used to make a fire waterfall at Yosemite; after the ranger did his spiel at the fire ring on top of the cliff, he would dump all the coals over the edge, creating a cool pyro effect. In Mammoth cave in KY, they would go into this big "room," turn off the lights, and then the ranger would throw a flaming oilly rag thing through the air. They even had lunch service in a special cave room. That was before radon was a concern.:neutral:
