When I worked in Flagstaff there was a guy on our (construction) crew who did fire fighting during the summer (back when fires had seasons). He told me a story about the Native American crews. He said one fire he was on they put the Apache camp near the Navajo camp. The Navajo were not happy about it. Then one morning they (Navajos) woke up and had all had the SAME nightmare. They were totally freaked out about it. They blamed the Apache and moved camp.
