I have a Kelty 40th Anniversary frame pack from many decades ago. Last used by me 24 years ago to carry quarters of a NH bull moose about a mile to the truck. I've used internal frame packs for hiking and camping for more than30 years now but the frame pack was much better for hauling the big loads. Any moose I shoot now will be close to a road so I won't be using the Kelty. If anyone is interested in it, please let me know.
