Understand, this tag is hard to get. I've basically been applying since I've been allowed to, and so has a ton of other hunters, It's an extremely limited draw. Each year you don't get drawn you will get a preference point. So, each year your odds will be a little better. But they only draw 60 some tags each year. Not many. The rest of your questions are answered here

Again, it's not an easy tag to get. You will wait years and years and may never be drawn. If elk is what you want, head west.
