Sounds like a real blast!  Hopefully it cools off a bit by then and you guys don't get rained out.  I seem to remember that it was usually pretty mild back there in September, though.  That is a bit too far for me to make it, and I am already committed to a black powder shoot out here in Colorado.
DVS, where are you going to be hunting?  It has been pretty dry in a lot of areas, the monsoon didn't have a lot of punch this year.  The Front Range is way below normal rain wise.
