You might consider taking some course ground pepper in your pack. On my last elk hunt we went light and of course killed a nice 5x5. My son-in-law took all our stuff back to truck to get both of our external frame packs. Some how in our haste we had left our game bags and pepper in the truck. I started skinning but had a heck of a time keeping the flies off while i worked. It was very hot so I couldn't wait. The pepper would have really helped keep them flies away. I would skin as far as I could in one area then lay the hide back on that area and go to another. Applied some pepper as soon as he got back and the flies were'nt a problem.
