Colorado Rocky Mountain-ish terrain. I do volunteer search and rescue. You can also see the news clip link in my last post as far as why I have a harness and such.
Also use these bags for personal hiking/camping fun as much as I do for SAR. Might not bring the helmet and such for a day hike with friends... but I still like having plenty of extra water, food, jacket, extra socks... etc.
So, i'm guessing the blue bag is for standard backpacking, and the green one is for day trips/SAR?
