The guy I left mine withdidit in 3 days! I was shocked that it was that quick! He had at least 100 heads in various stages in his shop(elk, deer, antelope, bison, longhorn steers, even a giraffe!).
I did pay $65 for it though. I didn't feel like skinning the head out and boiling it or waiting months for some ants to eat on it. The problem is that it is at a friends house in Wyoming and I won't get it until someone brings it down to me after Thanksgiving.
