Hi and welcome. It really depends on where you are and the attitude of those around you. There is always the chance that someone will call the police. There is always the chance that the police will be either unaware of whether it is legal or not, or just not like it personally and decide to bust your balls. I also refrain from open carry when I will be in a place where the focus should be on someone else, I.E. a birthday dinner, or if my wife doesn't want to deal with the possible hassle. It is all about personal choice and personal acceptable risk. It is 100% legal, and it is your right, and it is up to you to decide how often and in what situations you will exercise that right. There are minority camps here that believe you should never open carry, as well as one that believes you should open carry 24/7. Most of us, however, are sane and will advise you to simply carry the way you feel you should as the situation and environment dictate.
I have probably been approached due to OC or indirect OC.....IDK... maybe forty or fifty times. Out of those, one involved the threat of being shot by a PST, one involved being detained for close to an hour, and three or four others started off with people who seemed personally offended by just seeing my firearm. With the sole exception of the PSP incident, every one of these encounters ended pleasantly, with the people I encountered leaving more aware than when we met.
Know the law, and be prepared to assert your knowledge, because bad things can and do happen to us OC'ers. Hope you never find out though
