Lots and lots of hunters. Are you talking about big game? It has great big game hunting but require applying for tags. I know lots of Vegas guys and also CA guys that apply for tags in Southern Utah so you'll have lots of competition for those tags. Hopefully, you're not too old and will draw something before you can't hunt no more .
I keep looking at this thread and chuckling. I lived in Utah on and off for a few decades. There is LOTS of great hunting in SW Utah. Some of the best trophy hunting, really. But not for you.
I have a nephew that runs a hunting outfit down there. He wouldn't even give me a slot without a deposit and a two-year+ wait. That's the way it is: all private, in demand, and all pricey.
