I can appreciate the difficulty of elk. I have been responsible for the death of hundreds. So I have not always been a fat old lazy man. I used to be just fat. Now the old and lazy have come into play. One of the most difficult hunts on the planet is an unlimited sheep in Montana. I accomplished that one on my own. Big bulls in the backcountry. Been there done that. Now just a few on my hit list. Starting with the goat in BC next fall. One of the toughest hunts I have done lately is the Alaska bou and brown bear thing. Hiking the muskeg tundra is quite possibly the hardest thing I have ever done. I used to hunt mule deer at 12,000 to 13,000 feet in Colorado. I did a Wyoming moose hunt that tested my endurance. Twenty three miles in. That's a long walk out for a fat man. So you see, I'm not your regular couch potato fat man. Just getting frustrated at how my girth has restricted my life lately. I also admire guys who have the energy to dive into a big black hole like you spoke of. You would do it just to take a look and because it's there. I would have to know there was something in there to go in. I would also have to have a plan to get the critter out that hopefully did not mean all of it on my back.
