I'm not suggesting anyone hide the fact. I certainly don't.

But neither do I feel the need to introduce myself to a neighbor and tell them I have guns, (just so you know in case your kid comes over) or to use my PAL as ID.

If someone asks what I do for fun - guns. What do I spend my money on - guns.

Maybe I just have an aversion to bringing it up first.

"Afternoon officer, I feel I should let you know I have several firearms in the trunk".

As to the OP, obviously I don't think you need to let the neighbours know. Just make sure the kids can't access them. If the neighbours ask if you have guns in the house say yeah, why? Go from there as you see fit.
