Arizona Mule Deer Hunt

Hi Everyone
I will be hunting mule deer this january in Arizona. Unit 42 to be exact. The unit is all desert. Although I have never hunted mulies before I have hunted whitetails for the past 35 years. Any suggestions? In the desert area's is it pretty much spot and stalk? Do grunt calls work?
I just need someone to point me in the general direction
Any help or suggestions would be appreciated

There's a few big bucks in that unit......but it's one of the most difficult in the state to bowhunt, IMO.

spot n stalk.
