I guess you mean Utah?
I did see a nice rack on the other side of the road from a smashed in Honda car there last year.
'The law' was on scene. So I didn't know about the law or local etiquette on getting the nice rack, plus I was on my motorcycle, so how could I carry a 10 point rack? (Tied to the front bars, maybe).
Passing that cop was a good idea. Possessing antlers in Utah requires one of two things: 1. The tag/permit from the original kill. Or, 2. A bur at the base, indicating it was a naturally-shed antler.
Anything attached to a skull plate, without the original permit, is considered prima facie evidence of poaching. Any antler detached from a skull plate, without a natural bur, falls into the same category.
