Ray, 21 is an up and coming unit for coues deer. Off I 17 take Bloddy Basin road east to the Brooklyn Peak area. Glass the mountain from the west side and all areas east of there from the main road. I've seen several trophy bucks a year from there. You can be in the area from North Phoenix in about an hour. Have seen a few water at the dirt tanks on the extreme east edge of Perry Mesa. I have hunted Perry Mesa for mule deer, coyotes and antelope for a couple decades. The coues have increased numbers there over the years. Good luck
