Among the things to consider, such as the traffic safety issues and fuel economy benefits, I will need to come up with an effective, yet practical way to carry concealed during the hot weather months. My usual weekend cover garment consists of an untucked t-shirt or polo shirt. That obviously won't work when riding at highway speeds. Wouldn't want to scare all the soccer moms now, would we?
They might accidentally mow me down while trying to dial their cell phones to report the old guy on a motorcycle with a gun strapped to his hip. 
So...all you experienced bike riders...explain to this noob biker wanna-be, how do you carry during the hot weather months?
