Many have asked why I'm not going to DEFCON this year. In a word: Contractors. Don't let them in your house, because they'll never ever really leave.
I *could* go to Vegash and leave Mrs. K and Special K (our GSD, not her real name) alone for a few days with the contractors. I think that would probably use up a lot of, er...points.
But to me, leaving your home with contractors inside is a bit like walking away from a Microsoft Windows machine while it's rebooting after applying updates: You're just asking for trouble.
