All preference point schemes are a scam that would be illegal if not run by the government. The only proper system is a straight up random draw each year. Bonus points are just a watered down version of preference points, and just about as bad.
I've taken part in many of these systems for years, and even benefited by drawing some great tags. I've also been screwed by several states that changed the rules many years into the process (CO, AZ). Every state with these systems is always proposing some change to appease another special interest group, who is trying to get a leg up. These systems are politics at their worst, with one group always trying to screw another group out of their tags.
What these systems do is disenfranchise the majority of hunters in the country. Want to hunt "the strip" in AZ, if you haven't been in the game from the beginning, then go pound sand. In Utah, you can get your check book out and pay for a tag, buying your way to the front of the line. Heck, even an elk tag is effectively a once in a lifetime tag in Utah, unless you buy an auction tag. Not to mention sheep, etc.
WY points for sheep started out at $7 for NR, and are now $100, and proposals to further limit NR tags are always in the offing. If you haven't started acquiring points, then their is really no hope. How do we justify excluding the vast majority of hunters from participating in these hunts? We will never have enough sheep tags to issue to everyone who wants one, so do a drawing each year, and let the chips fall where they may. A kid that gets into hunting in his 20's or 30's can NEVER be competitive in these point systems. So we favor the old guys (like me) who think somehow they are more deserving than the newcomer. Bullshit. I've drawn tags in states with random draws, and not drawn tags in some of those states as well. I couldn't give a damn about AZ anymore, because I am so far behind the curve as to be mathematically impossible to ever draw. Do we really want more people giving up on states, and not worried about conservation, etc., because they are disenfranchised?
Go back to random draw in all states.
