I'm agreement with Guy...almost. I know the sheep thing is a mess but in the case of moose I think the point system is working really well. I have been the recipient of 2 moose tags. The first was through the random draw in '93. 2 years later they went to the point system and I was not grandfathered in. I waited my 5 years and then started applying. I even forgot to put in for my tag one year so I was now 3 years behind everyone. Well, after diligently applying for many years I drew my second tag in 2008 because I had enough points for my area which I'll add was a very good area (I got a Booner). Now the 5 year waiting period is up and I can once again start applying for moose and I do expect to get drawn one more time (albeit I'll be kind of old when I do).
I also drew a sheep tag through the random draw in '94. Same story as moose except I'm 4 years behind max points. I could be seventy when I get another tag but I plan on getting one.
Like Guy, I would hate to see deer and elk got to a preference point system but maybe it would work for antelope since all the tags are limited quota anyways and I don't think people get quite so devoted to drawing a specific area when it comes to antelope tags like they do for elk.
Just my 2 cents.
