Buckhunter,
Shoot it, find it, and get to work. Bone it out completely using the gutless method. Get the meat into good game bags and get it cooling. Hanging the bags in the shade is good, but, if you can hang it in a cool creek draw, you're golden for up to several days, weather dependent. Have the big coolers w/block ice ready back at the trailhead to drop your meat in for the ride to your ranch or the processor. I have shot elk in SEP where daytime temps were in the 70s+ and have had no issues taking up to 4 trips (over the course of 2 1/2 days) to get the meat back to the coolers. Again, you've gotta get the meat cooling quickly and hung in a place that will keep it cool until you start packing it out. Good luck this fall!
