If you want to continue hunting you'll need to find a list C tag. These are unlimited and it doesn't matter if you've had an A or B list tag. These types of tags are generally special population control tags or ag damage control hunts and are hard to find out about in time to get a tag. Sometimes the DOW will send out a press release informing the public of these tags.
Best plan now is to look at hunting other big game besides elk or perhaps elk in another state beside Colorado. I don't elk hunt much outside of Colorado so not too much help there.
You can always start planning your hunt for next year too. Only 350-ish days until the season starts!
I have a mulie tag for this week. Unfortunately I used all my vacation for the elk hunt. I will give it a shot this weekend since it closes Sunday. I may need snowshoes at this point with this snowing thats being dumped.
When it comes to scent, there are basically two types; those that attract and those that mask. I've tried both on many occasions. There are lots and lots of "doe in heat" scents, designed to attract a big buck into range. I've also used a "cow in heat" scent while elk hunting.
Another scent would almost be better named as a "coverup smell". The main goal is to cover up human odor or mask it. Though I don't believe you can ever totally eliminate all human...
