I wish it was my picture, it's circulating like crazy here in Eastern WA, but my nephew sent it to me, (He's 12 and a hunt/fish crazy nut) so I've emailed to find out where he got it. I've got it from several other sources too, but they are all obvious forwards from other people, so they won't know where it came from.
My wife, like Len, takes pictures for a living, so I don't like using pictures that aren't mine. There has been no attribution for this picture yet, though, in several days.
The strongest reason for the people to retain the right to keep and bear arms is, as a last resort, to protect themselves against tyranny in government.
