Not that i'm trying to bring more hunters here but this is the truth. This is written by the Meateater.
Colorado
Colorado is widely regarded as the nation’s top mule deer destination. Due to
extremely good mule deer habitat with plenty of food and sound management practices by Colorado Parks and Wildlife, the state has the largest mule deer population in the country.
More big bucks are killed here every year than in any other state. Mule deer tags are only available through a limited draw here; you have to apply for a unit-specific tag for either archery or rifle seasons. The good news is there is an abundance of units where tags are easy to draw. There is no need to spend years applying for well known “trophy units” since you can find good bucks just about everywhere in the state. Public lands are abundant in the western half of the state but very limited in eastern Colorado, although some of the biggest bucks are shot out on the eastern plains.
Archery season runs from late August until late September. During this time, mule deer in the Rockies are found at high elevations, often above treeline. Rifle seasons in the mountains take place in late October and the first half of November. Depending on weather and timing, mule deer are widely distributed anywhere from high country summer range down to low elevation wintering grounds. On the eastern plains, some rifle seasons run into December. I may be biased, but if I could only hunt one state for the rest of my life for mule deer, it would be
Colorado.
