I drew AZ Unit 1 late rifle in 2006 w/ 10 pts. I had been putting in for early rifle hunts, but finally gave up.
The Unit 1 late rifle hunt was tough - lots of hunter disturbance - few mature bulls. I hunted hard and ended up killing a 330 pt. 6x5 on Escudilla Mtn., which was the biggest bull I saw. All things considered, I was very pleased with the hunt and with my bull, but it would have been nice to have at least seen a 350+ bull.
I also visited Unit 1 in late September, during the archery season, to stay with some friends with property there. It was awesome. We had bulls bugling around us all night, and I was able to stalk to within 40 yards of a huge 7x7 on my friend's property (couldn't find the bull again for the late rifle season). The bugling activity began about 30 minutes before dusk and ended about 15 minutes after dawn, with almost no bugling during the middle of the day.
I stopped by a number of bowhunter camps and saw a few 350-360 class bulls. It seemed that most guys were up on the mountains by late afternoon, trying to intercept the bulls as they descended to make the lower meadows by dark. This process was reversed for the morning hunt. Relatively few were hunting over water (the late summer of 2006 in that area had been relatively wet), or were having much success attracting bulls to calls in the middle of the day.
Unit 1 is a great area with a lot of good habitat. But from my experience, there are few pockets of undisturbed areas where people don't go. I'd stay to the higher levels of the more rugged sections, but I am sure there are plenty of guys here who know Unit 1 better than I.
Good luck,
