I was on a free range Aoudad hunt in Coahuila Mexico last month (as camera man), lots of extreme hiking and/or climbing, the terrain where they live is really hard. A friend of mine has a property with access to a part of the mountain range where they live, I can hook you up if you want (the area has not been involved in drug war violence as far as I know, I was there last weekend again this time for javelina hunting) however the % of succes is very low........with a rifle! no one has taken one with a bow and arrow there yet(compounds included) but they do guarantee you will see them otherwise you wont pay.
it will never be the same to chase them in the mountains as to hunt them in a fenced property (I'm not saying its easy)As far for the DIY you can do it or you can hire guides
