In Colorado's Unit 136, hunters have shared experiences of challenging river crossings along the Purgatory River, with the water being deeper than expected, hindering easy access to hunting areas. Some hunters have found the river difficult to cross without waders, suggesting preparation for these conditions could be advantageous. Access to the Comanche National Grasslands for mule deer hunting is possible, and contacting the local wildlife office can provide insights into optimal entry points and local wildlife activity. Overall, engagement with local resources such as biologists and game wardens is recommended to improve hunting success and understanding of the terrain and deer movement.
