I live in AZ, east valley of Phoenix. Open carry & CCW are both legal here. I carry concealed unless I am out hiking in the wild.
Yes at 105 degrees it is warm, but a square cut light weight shirt from Cabela's or Bass are cool, comfortable and very concealing. I prefer not to advertise my capabilities. If I do encounter the BG, I would prefer to be a surprise
. JMHO
Seems I once read that carrying a gun is supposed to be comforting, not necessarily comfortable.
