As a former service member myself, I can appreciate your time to hunt dilemma. I'm glad that the servicemen of today seam to be more appreciated then the servicemen of my time (viet nam). I thank you for YOUR service.
I also drew a Sheep tag this year for a unit I know nothing about. But the great people from this forum have given me lots of info. Not like what rock to look behind but things like get in shape, scout the unit if you can (I scouted mine for a place to camp and actually saw Sheep), take bug spray, pack light weight everything, and much more. I hope you can drive closer to your unit then I am able to on mine, I can only get to with-in 6 miles. I didn't know the Sheep that I saw were there until they kicked loose some rocks and gave me a direction to look with the binos. So keep your ears open.
Congrats on the tag and good luck on the hunt but more importantly be safe and have fun.
