I am a farmer in Colorado, east of Denver on the plains. I don't own the land, my family does. But I help manage the land owner tags for our family. First of all, Scoutman is right, John Flier is the man that manages all of the land owner tag for the state. Every time i have talked with him, he has been really helpful. I can tell you that the minimum acreage is 160 for one tag, which is a quarter of a section (a section is a square mile of land or 640 acres). They can get a little picky on the acreage, my aunt owns a quarter that is 157 acres and they denied her a tag. The land owner or entity that controls the land applies for a tag through the old fashioned paper application. The deadline is the same as normal big game draw for everyone else, April 6th this year. It also cost the same for each application, $7. The land has to be enrolled and registered with the state for the land owner preference point program. John can walk you through how to do that, but you will need the exact legals on the ground. Once you have it all set up, the land basically acts as an individual, if you don't draw your first choice you get a preference point. Oh and I forgot to mention, the tag is only for the unit in which the land resides. If you draw a tag, it comes in the form of a voucher, which then you have to go down to CO parks and wildlife office or any where tags are sold and pay for the actual tag. Hope this helps.
