Outfitter is labor overhead
It costs because it takes a lot of personnel time to do it right.
If it's more than a mile of hiking off road, it means outfitter for most. Hunt in a new place, more than two, three, four miles, from a trail or road, it means ways to transport the hunter, and transport to get the harvest, back to where the hunter can get home.
With the internet, the cost could be too expensive for many outfitters. It might be so expensive, that fewer and fewer hunters can afford it. Thus even more complaints for even a pretty good job.
But what is a hunter to do, the road two miles from its harvest, and wolves or coyotes ready to lunch on a lone hunters harvest. While three days away from a cooked meal. What's a modern hunter to do.
I don't use outfitters, but I can sure know many are essential for many a hunter.
