Hunters considering Unit 15C in Arizona for late archery OTC mule deer hunts can expect low hunter presence, which is appealing despite the sparse deer population. The rut generally starts in December, with peak activity around late December to early January, which might aid hunters during the January dates. Though one hunter chose to explore Unit 20A instead, they found spotting bucks relatively feasible but faced challenges due to open terrain that makes stealthy stalking difficult. This feedback suggests that while both units offer sightings, honing spot-and-stalk skills and understanding the terrain are crucial for a successful hunt.
