I hope you have a good bank roll, Aoudad are getting pricey.
If you can, look for free ranging sheep. I have taken them in the Palo Duro and Big Bend Regions in Texas. Contact the Chamber of Commerce in Alpine Texas (432/837-2326). They have a list of guides for the entire area. Best advice is to be in shape and have one flat shooting and hard hitting rifle. These animals are tough. Hard to pick the best area.
Good sheep all around the areas. When hunting in the Big Bend area I do it in Jan/Feb. It gets pretty hot down that way. The Palo Duro sheep can be hunted a little earlier, Nov/Dec is a good time for them.
