Buskill, There are more and more high fence deals popping up but for the most part sheep are free range. The question really needs to be asked if booking a hunt. I almost made that mistake several years ago. Looked like I was going to get a great deal and at the last minute I asked if it was a free range hunt. Glad I asked! GSCO and WSF do not willingly accept high fence rams BUT if the hunter lies about it or neglects to tell the truth who knows. Again the conversation returns to ethics.
Like Jim says, make sure you ask BEFORE you go.
I believe all hunts on Carmen Island and Tiburon are considered fair chase as well.
Make sure you ask questions BEFORE like Jim and kota-man advised! There are quite a number free ranging hunts to be had if your pockets are deep enough.
When I accompanied my father in Sonora on his DBHS hunt to complete his FNAWS, we pulled into camp and saw a fence. The "oh shoot" (different word) came out of our mouths. I told my father that I would inquire with my broken Spanish as to the fence. I told him that we were leaving if it was high fence, as he has gone too far in his life to kill a pet.
Luckily, the sheep were free-range. It was for some Couse and Mule Deer high fence deal they were starting.
My father ended up with a 179" ram on his second trip. I started a new job and couldn't accompany him on the second trip.
100% agree that these have no place in the books and awards. There are three sure things in this world: death, taxes, and a high-fence hunt.
