"I've got another letter, and this is from Sim, regarding off body carry. Is that like an out of body experience? No, here's what it says. Hello, I would like to start off by saying I'm a huge fan of the show. And thank you for being a fan of the show. And all the information you provide on the show. My question is about off-body carry. My understanding is the new carry law requires a firearm to be on your person. Would a firearm in a crossbody bag / fannypack be considered on your person? Also, I was considering carrying in my gym bag. Would that be permissible? Thanks in advance. So, here's the deal. If you actually look at the statute under N.J.S. 2C:58-4, and you go into the little subsections down where they have the point two (.2) and point four (.4), etc., you will find that it talks about how a holster is defined. It has to be in a holster. This is very important that it is in a holster that meets the criteria for being a holster, and it does say on the person or about, on or about the person. That language is used there, on or about. [See 2C:58-4.5(6)(a).]

So, what it means is you either have to have your firearm, no matter what in a holster, but if it's in a holster, and it's ***within your direct control, your direct dominion and control.*** [Emphasis added.] For example, if you're a woman and you have a carry purse, and the carry purse has a holster inside the purse, you're now, as long as there's a proper holster that covers a firearm, covers the trigger, secures it properly and meets the criteria for being a holster. It doesn't need to have a thumb break or a snap. That requirement was gotten rid of by way of the Association lobbying in Trenton. We were able to get rid of the requirement to have a thumb break or a thumb snap or a strap. But it does have to completely secure the firearm. It has to cover the trigger guard, etc. If you've that holster in your purse, and the purse is being held by you, or directly ***on or about your person, next to you,*** the same with a fanny pack. [Emphasis added.] If it has a holster in the pack that meets the grade, most have a Velcro type holster that goes inside the purse or pack so that the gun doesn't just flop around in a purse or in a pack or a backpack, etc. There should be a separate holster within the bag. As long as that is on or about your person, then you're okay. But if you're in a car with such a thing, don't go put it on the back seat where it's not in your control. Make sure it stays directly about your person. That's the key to New Jersey carry."

I called US law shield and this is what one of their attorneys left on my voice mail.
"Good morning David this is a return call regarding your request for US Lawshield callback from the New Jersey attorney you didn't answer so we weren't able to speak unless answer your questions pretty straightforward there is no answer to boardwalks that is not a legal category right so boardwalks are just gonna be the same as any other property meaning that you have to do a full analysis under the private places senses various analysis some boardwalk do constitute state parks some boardwalks constitute entertain facilities some boardwalk serve alcohol some boardwalks are private property. if you don't know your best bet is to call the local PD and ask about a particular boardwalk and see what they say. there is no legal category of Boardwalk per se it's it's just like every other property of the full analysis of the prohibited places make sure that it's not a public gathering entertainment facility casino property so it so forth OK "
