Uh-oh

Not only a bad day overseas, but a very bad morning shaping up on Wall Street. The Dow futures are presently down -548.

I'm going to be out in the real world most of this day from here...as opposed to hanging out here in the world of elites. But it may be quite the day on the roller coaster.

This DKos diarist says many futures markets have been frozen.

Once again, this may be the day we find out if brokers can fly.
