Most of the time I CC
I would say that it is still about 65/35 CC/OC
I tend to cover up when I'm going out with friends, or going places where I may not want to keep so much attention focused on my pistol in the open. When I OC I tend to stay more alert, on edge maybe? Close proximity to many people with my gun exposed makes me somewhat nervous still.
I also cover when I am going to a friends house or to play poker, etc.
Since I OC for either a deterrent or educational purposes if the situation does not call for either then I will conceal more often than not.
Of course, there are days I just don't want to bother with a cover shirt...
