I might be wrong with this but here goes. Here we are not required to inform. If its just a traffic stop for something minor its probably best to keep it to yourself. I've seen some leo's make a big deal out of any firearms in cars. It can make a short traffic stop into a long drawn out affair. Out here even having a large amount of cash on you can get you looked at real hard and it can even be confiscated, and this is a gambling town, lots of cash gets exchanged all the time.
