Welcome to the forum Gregg. I joined the forum about a year and a half ago and most in here probably still know more about guns, and carrying, and rights and such than I do. I would just say that if you keep coming and bringing up topics and asking questions you can learn alot about guns, rifies, calibers, concealed vs open carry, etc. The bit Navy just posted about how much faster it is to draw open vs concealed is something I've been thinking about lately. I generally carry with a tshirt or sweat shirt covering my gun that's easy to pull over the gun while drawing, but as the cold weather comes having to draw from under a coat is a bit more cumbersome and time consuming.
It's likely I will never have to use my gun for self defense, but we never know and my reason for carrying is to have a chance if I do come up against someone who wants to shoot me. How quickly I can get to my gun if that happens is critical.
I open carry out in my yard because there are alot of big dogs in my neighborhood, but still conceal in public. Right now I am looking into how I can conceal with a coat on and still have easy access.
