The former N.M. State Historian Roberto Torres in the 1990's was asked to come up with an official history for a walking tour of Santa Fe so that tours conducted by various individuals would be consistent, accurate, and enjoyable; and wild claims in such tours as: "Billy the Kid shot at Abraham Lincoln here at this spot" would be disspelled.  Often tour guides just made up stuff to have a unique tour---such disrupetableness could fall back on the hotels, resturants, conferences and tour companies which were associated with them.  The walking tour was submitted to a City Council-appointed committee for approval and additions; and the whole "script" was tested on some actual tours.
