If you are doing a elk hunt in Colorado in a couple of weeks and you don't even know what units you can hunt in, you better get on the stick. My achery tag is state wide except for Ltd units, I would think yours is the same, unless out of state is different.Atv's are allowed in the blm where we hunt, but all areas are different. You need to google DOW Colorado check out our web site. There are plenty of phone numbers for you to call. If you're the organizer, you are way behind, and you could look kind of foolish if you don't do a lot of work fast. If you cannot find the help you need, give me a call and I will hook you up with someone who can answer all of your questions. You should be fine with just calling our DOW, they go above and beyond when you need help. They will also go above and beyond if they catch you hunting where you are not suppose to be or breaking any other law! Good Luck!
