So, while I probably don't have to worry about a major earthquake killing everyone in the DC area, I do have other things to worry about. More than once a Hurricane or Tropical Storm has veer north. Snowpocalypses. And the ever popular terrorism. Not just regular terrorism, mind you, but considering it's DC we're probably on the short list if someone gets ahold of a nuclear weapon. I've actually pondered it and determined that I would probably be okay if a nuclear bomb went off in the District or at the Pentagon, as my apartment is sufficiently far away and some nutjob is unlikely to get ahold of a truly large nuclear bomb. If I can get the direction of the wind in, say, 30 minutes of the bomb going off I figure I can be out of the area before the rush occurs.
Speaking of apocalyptic problems, I swapped out my cats open top catbox with a closed one. One of the cats is very put out at this, and I've seen her walk up to the enclosed box a few times, come to a complete stop as if she just realized it was there, and very carefully ease her way in. I don't think she likes it, but at least she isn't showing her displeasure by peeing and pooping hither and yon.
