Thankyou. You guys are great! Although being a aquatic biologist, I never given much thought to this situation. I have always been iffy on boning out an animal and hauling 130# of mush on my frame pack. Too tough to strap and mush around and 3-5 miles takes some time. The water temps are mid 40's, which would maintain cool meat during the day. I use pillow cases to wrap the meat, although I think placing them in garage bags before the stream would be an excellent idea. Thatwould maintain the recommended dry. Thanks so much.
