Ahem, speaking as an archaeologist, tenuous member of the Choctaw nation and Tonalea elementary school alumni in Scottsdale Arizona ( heavy AZ tribe population) I feel somebody should remind the brownies about Apache customs. One NEVER refers to a departed Apache as a ghost, if indeed at all in open conversation. It's rude. Sometimes a shelter is called for and sometimes a fire. Survival isn't chapter 3, page 38, paragraph 4- this is how 'grandfather' did things and it's required for all situations, including those no Apache has ever encountered.
