Dr. Bill Austin of Flagstaff, a renowned doctor there, who is also a veteran Canyon hiker, once told me, after I had camped in a cave on the Bill Hall Trail, that camping in your tent in the cave is not going to help you. You can't avoid breathing the dust when you put your tent away, for example. He recommended that we should have set up tents out in the open. Actually, we didn't even have tents, which was why we sought shelter under that big ledge. (Some of you, no doubt, know which ledge on the Esplanade I'm talking about.) Anyway, I respect him highly and think he probably is right about that. Despite seeing many mice none of us got the virus. This was in 1993, during the time the virus was first becoming very well-publicized in the Southwest, and after there had been a number of deaths on the Navajo Rez. We had all been warned about it, but it was pouring rain, so we camped in there.
