The City of Scottsdale has posted its policy prohibiting Geocaching in
the McDowell Sonoran Preserve as the second article on this page:
http://www.scottsdaleaz.gov/preserve/currenttopics.asp.
 
As far as I know, the Preserve joins the Bureau of Land Management
(http://www.blm.gov:80/nhp/efoia/wo/fy02/im2002-017.html
<http://www.az.blm.gov/pfo/index.html> ), Maricopa County Parks and
Recreation (www.maricopa.gov/parks/news/),  and the State Land
Department
(http://www.land.state.az.us/programs/natural/rec_offroad_permit.htm) as
the only agencies in Arizona to have posted their Geocaching policies on
the Web. If you know of any others, I'd appreciate hearing about them.
