Most of the friends I made in my CHL class all carry 24/7. However, I can understand the emotional feeling that some people believe that "If I am not carrying, nothing will happen to me today." They, wrongly, believe the very act of carrying might be the reason BGs might assault/rob them. Of course, this is not rational thinking.
I am a true believer. After three incidents with BGs, I don't need a fortune teller to tell me I had better be prepared for the future. I now carry 24/7 to be prepared for when something else does happen. From my experience, this is a highly rational decision.
December, 2010: Gym locker robbed
November, 2011: Accosted outside a nice restaurant and money demanded
January, 2012: CHL in hand, 24/7 carry
December, 2012: Attempted but failed carjacking at 4:15 p.m. outside a nice restaurant.
Something above tells me that my situational awareness needs to be on high alert from Thanksgiving through Christmas each year.
