Elton, you almost have to be a lawyer to interpret all the regulations. Each state is different. I live in Colorado where it is basically a manual for hunting. We have a number of big game species such as mule deer, whitetail deer, antelope, elk, moose, bighorn sheep, mountain goats, black bear, mountain lion, etc. each has different license tags for different seasons. You have to pass a hunter safety course before you can even get or apply for a license. For mountain lion, you have to pass another online test as well.
There are a few game management units where you can buy an over the counter bull elk license, but lots of units you have to apply early in the year in a drawing to get a license. Some units you can get an over the counter tag for black bear while you are hunting other species (elk, deer primarily).
Almost everything else you have to apply for preference points each year and pay to get that until, or if you ever get drawn. Example: apply for 3 years just to be able to get the initial 3 points before you start getting what are called “weighted” points after that. I applied for some 18 years for mountain goat and bighorn sheep. After the first six years, I lost all my points because I failed to apply on time the following year. I started over. Now at 73 years old after acquiring 12 weighted points, I’ve decided not to waist my money and time chasing a dream I likely will never draw and if I do, I likely will not be in shape enough to hunt at 12-14,000 feet in elevation.
Another example: I had 12 weighted points (plus the 3 to start) for moose. I gave up on a bull, and decided a cow would work. I drew and lost 15 years of points and many $ of applying. I had to hunt alone, so I knew I had to drop a cow within 300 yards of a road, or I would never be able to get it out. No cell service and 75 mile drive to call for assistance. Needless to say bulls walked across the road in front of me, but all the cows were 1/2 mile at least from a road. Didn’t pull the trigger on any. 15 years of points gone.
Not wasting my time and money chasing points in Colorado. If I really want a moose, bighorn or mountain goat, I’ll go somewhere and pay an outfitter to haul it out.
I drew an either sex elk tag and a buck mule deer muzzleloading tags this year. If I take them and can get them out without a heart attack by myself, this will be my last year without a guide to do the heavy lifting.
Hope this helped you understand one US state’s licensing method.
Best if you are planning to pursue North American game.
