Smiley is dancing in the street because concealed carry has been passed, in one form or another, in all fifty states now. However, so many other articles have been or are being buried that being able to carry a gun will be about all you have left. Remember the 4th Amendment? How about the 5th?

Right now as I write this, our beloved president is busy trying to figure out how to make "executive orders" that will bypass Congress, thereby taking out one of the legs of our "checks and balances" system-- speeding us to the day when we will have a dictator in the White House. Frankly, I don't care if the dictator has a (D) or an (R) after his name, a dictator is still a dictator-- and those have proven to be bad business.
I wonder if Canada has room for refugees? There may be more than a handful if things keep going the way it's shaping up that they may go.
