You're getting some good advice here. I would add this too though. If you're muzzleloader hunting, coordinate your research questions to include where the Elk are that time of year. Around here, there are entire game management units that don't see the large populations of Elk until the weather or other factors move them into these areas. The harvest data may be decent in a certain unit, but it might be either from early or then late season hunts. If the Elk stay in their Summer & Fall ranges, it probably isn't a good idea to opt for a unit that these Elk move too later in the Fall.
Unless you are really tough, have pack stock, or use an Outfitter to get away from the roads, I'd expect to be seeing other hunters in Colorado. That's just the way it can be.
