Been a while since I lived there but when I was there unless you were traveling directly to or from a sanctioned activity, range, shop, smith etc. you were not to have any firearm. Said firearm better be cased and unloaded. At least when I was there loaded magazines would bring grief to you. We were not to stop in between said sanctioned activities either. No running by the store on the way home etc.
That being said ownership laws were not that bad.
If I were you I personnally wouldn't have a firearm unless you are passing through or heading to your stopping point. But that is just me.
