All day on mothers day at the Fort Wayne Childrens Zoo. No one said or even seemed to notice. Got home and was working around the yard and my neighbors noticed for the first time. The daughter said loudly "mom he has a gun!" Witch caused the husband to run outside and interigate me. He said he was going to call the police but I informed him I was licenced and on private propert so I would love to have a friendly conversation with the PD. He called me a few names and went inside. A few minutes later an officer showed up with lights and siriens going. Apparently the call was made about a man with a gun but no mention of the licence. The oficer was friendly and said he was just checking out the call. No problems from him at all. My wife and daughter got a good laugh out of it all.
I wouldn't have even mentioned you had a license. The license is a complete non-issue since it isn't required, nor would it even be a factor since you were on your own property. I'd probably be scheduling to have a chat with that neighbor. Sounds like he needs some education not only on the laws but on common courtesy.
