Hunters have had a challenging experience in Colorado's Unit 139, particularly with regards to the scarcity of public land, which complicates access and hunting efforts. The reports suggest a low density of antelope and very few sightings of legal bucks, alongside skittish behavior from the animals due to frequent vehicle presence. For those planning to hunt here, it's crucial to prepare for limited opportunities and consider alternative units with better public access. If camping is necessary, ensure you're aware of legal parking areas to avoid any issues while using a truck bed for accommodation.
