I had this tag in 2007. You will get one with that number.
The hunt itself is usually pretty simple, but a warm fall like last year will keep most of them in the Park where you can't hunt.
Not sure where you are from, but be prepared to get a bunch of meat out quickly. The carcass weight of mine without the head and hide was 800 pounds. It filled the back of my shortbed Ford.
I used a 300WM, but any good rifle at least 30-06 or more will do the job.
