Tipping depends on success, attitude of guide and your conscience.
I was on a moose hunt in Newfoundland a few years back. It was the trip of a lifetime and I had a guide that did a great job and put me on the biggest bull of the four that week took.
In the end, I gave him a $400 tip and new DMT knife sharpener. I also tipped his wife-who was the cook. They were beside themselves with gratitude.
They needed that money a lot worse than I did and that was part of my decision to give generously.
Good man. Great post.
