Asher/Rmyoung - I am coming from the side that I would give anything to add a couple of extra years to my families elk camp and my fathers comfort. My dad turned 85 earlier this year and 2years ago was last time he could make into our elk camp that we found and have been using 47 years. We have had/owned upto 8 horses and now I am down to a couple of old ones. I trade/borrow horses with our vet and have some older bow hunters we swapout horses with when they draw. I would rent horses if I had too. The tradition will continue now even though my dad physically can't make it riding a horse or walking in.
I will go into this camp a few weeks from now and spray weeds, and cut firewood for the upcoming season. I will visit this camp the weekend before the openor and pack in other items if I don't have the necessary stock to get everything in - in 1 or 2 trips. I have found other old crap left primarily by backpackers or dayhikers that put an animal down to far to pack out timely(broken game carts etc )or horse packer wanttobees that found out how much work it can be to get that far in. Horse packing is easy when the trail is dry and the horses know the trail - which is about 1 in 3 years the trail is good. I routinely pack out trash by others.
Maybe I am digging my whole deeper, but you could always - assumming you are packer come in sometime earlier and pack in some this heavy stuff.
Or if you decide to bury it properly where no one can see it and then abandon the camp, then pm the coordinates and I will probably pack it as that is the type of person I am and meet you somewhere to return the gear.
Happy Hunting as I am sure you are finding out - it is a heartbreaker for you and him realizing the good old days are long gone and now you just need to make them as happy and comfortable as they can possibly be - before they wake you up at 3am a couple of days into the hunt and tell you this is the last hunt and they would like you to pack them out with the next load to the trailhead.
