My wife, parents and some friends know that I do carry (ie that I have my permit). They (except the wife) don't necessarily know WHEN I am carrying unless they spot it. AFAIK this has only happened once, when a friend figure out what was in the fanny pack I was carrying one day when I was on a walk (was in gym shorts and a t-shirt so no where else to conceal the gun). He's a permit holder so I'm guessing he knew what to look for, plus those things only conceal the weapon in the technical sense (you don't see steel) but they kind of advertise it's presence. Reason #1 why I don't like carrying in a fanny pack.
