I plan on living and dying having never been guided on a hunt. If I have any interest in hunting that is the only kind of hunting I am interested in. Those are my standards alone, and to each their own free of judgement. It is true that this reduces the opportunity for varied hunts across the globe, and I suppose my perspective could change, but there is a lifetime's worth of hunting within 100 miles of my front door.
In my opinion, you're missing out on some of the best hunting in the world, and for a great number of species of animals that we don't have at home.
I started hunting in my native state of Colorado, and for the last 44 years have successfully DIY hunted deer, elk, antelope, bears, sheep, moose, and goats within 100 miles of my front door. Years ago some friends and I did a DIY caribou hunt in Alaska, and had a great time. That hunt also opened my eyes to a great world of hunting beyond my home state.
After 35 years of my DIY hunting at home, in 1999 I went on my first guided hunt that was for Dall sheep and Mountain Caribou in Canada's Northwest Territories. That was a backpack hunt for two species of animals that we can't hunt in the lower 48 states. That hunt also involved a float plane flight into the base camp, and a Super Cub flight further into the McKenzie Mountains where the hunt took place. Beside the fact that Canadian law requires non-Canadian residents to be guided on big game hunts, the outfitter provided those flights and camps. On the actual hunt it was just the guide and me in the wilderness, and he didn't "hold my hand" on the hunt nor did he tell me which animals to shoot or not to shoot.
Since then I have gone on two more Canadian big game hunts, a half dozen hunts in Africa, and on hunts in New Zealand and Azerbaijan. Although it is possible to do some non-guided hunts in Africa and New Zealand, especially in Africa, it would take a lot more coordinating and planning to do a non-guided hunt, and I doubt that I would have been as successful as I was with a guide. Just the difference in languages would make many non-guided foreign hunts very difficult, if not impossible.
I can and have hunted and processed just about all of Montana's big game animals by myself, but at home I have all of the time I need to do that. On foreign hunts, I have limited time, equipment, and knowledge of the game and area. I would rather spend my time hunting in those countries, and leave the other work to the outfitter.
