The comments on Unit 29, Arizona, emphasize the challenges and dynamics of hunting there, especially for Coues and mule deer. Hunters highlight the importance of glassing from high vantage points due to the small size of Coues deer and the need for precise spotting, mentioning that calling is generally ineffective because of the low buck-to-doe ratio. Recent trends indicate a decrease in trophy quality due to increased pressure from rifle tags and over-the-counter (OTC) archery hunters, making the unit more crowded than it was a decade ago. For those considering a hunt, advice includes preparing for varied terrain, checking water availability in the wilderness, being aware of potential human trafficking issues, and understanding the mixed results of deer population data due to combined reporting for mule and Coues deer.
