I thought maybe some of you might be interested in this.  Sorry if this is
too off topic for some of you, but I have participated in The Hunt for the
past 4 years and found it to be a lot of fun.  As a matter of fact, I've
seen several puzzles from past hunts turn up as cache puzzles!

The gist is this.  It's a treasure hunt that take place in the
north/northeast valley in the late evening/early night (6pm-1am).  This year
it is on November 16th.  There are about 75 teams of 6 people that
participate.  There are 26 different clue sites that can be found (not that
you could possibly make it to all of them within the time allotted).

Standard treasure hunt protocol for the most part.  All teams begin at the
same point and are given a map of the hunt area with ~100 possible clue
locations marked and directions to your first stage.  The teams begin in a
staggered fashion (one every 30 seconds or so) and begin at differing sites
(first team goes to site A, second team to site B, etc. until they repeat
and team 27 goes to site A, etc.)  When you arrive at the first site, you
will need find a clue/puzzle that you must decipher in order to find the
next site.  Remember, this is taking place at night in the desert so it may
take some searching (and, no, there's no GPS coordinates for the locations,
only the scale map!).  This continues on in this fashion until the hunt ends
at 11:30pm at Pinnacle Peak Patio.  The results are tallied while the
players get dinner (buffet with steak, chicken, lasagna, etc).  The team
with the best time per clue average is the winner (and agrees to be on the
planning committee for the next three years.  The team that comes in second
is the real winner...)

Disclaimer: I have nothing to do with the planning, organization or proceeds
from the Hunt.  I am only a participant, having come in as high as 16th last
year.  I am happy to answer any questions you may have about the Hunt, just
let me know.
