Another Reason: Can't Carry In "Hunting Preserves"
Yes, get a permit.
The Utah Dept. of Fish and Game have a rule--and their rules carry the weight of law--that you can't possess a firearm in many "Temporary Hunting Preserves" unless you're licensed to hunt there, the police, protecting your livestock, or licensed to carry concealed.
This Rule applies to many (but not all) big game hunts (and possibly other hunts). There's usually some sort of big game hunt going on somewhere in the state between August and December. And you need to know each boundary (just understanding the boundaries--now there's a mind-blowing task!), the hunting dates and which Big Game Hunt is a Preserve that excludes unauthorized guns to be in compliance--a nearly impossible task! So unless you want to spend days and days studying every possible hunt date and boundary the Fish and Game has going, you can never be sure that when you're in the mountains you're not breaking their "Rules."
This "Rule" of the Utah Fish Cops seemingly is not even preempted by the Utah State Law that states, "It is lawful to possess a loaded firearm in one's residence, temporary residence or camp."
Now, I firmly believe in obeying the hunting and fishing laws, and for the record, I've never been cited for a violation, and the Fish and Game--God bless 'em--have a formidable task in enforcing these laws; but I've never met a Fish Cop who has an even remote sense of humor about their rules. (Just ask my buddy who was chastised by a Fish Cop for simply "looking on the wrong side" as he drove down a dirt road that was a hunt unit boundary!)
Get a permit--where I work, we'll call you a "certified good guy."
