If you can draw the tag, I have not found the hunts to be too terrible difficult, If you will spend the time to learn the country.

I did a DIY hunt for a desert bighorn in 2007 and helped a buddy with a Rocky in 2008. The unit for my Desert Bighorn was 100mile x 100 mile square. Or about 1000 sq miles. In that 1000 sq miles were unlimited canyons, draws, shelfs etc. So if you count all the verticle, it was 4-5x the surface sq miles. In my unit they figure there are 300 sheep. So you are looking for a needle in a haystack.

I spent a bunch of days searching the country with out seeing a sheep. Once I figured out where to look and got into the right part of the country, I saw 70 sheep in 3 days. So it's just getting into the right place.

The following year, as I helped my buddy with his tag, We found the sheep the first day, Saw 80 sheep and harvested a nice ram late in the first day. Mostly because of the experience I had gained the year earlier.

Fortunately I live with in a 4 hour drive of where I hunted
