Hawkfyr:

I work in Greensboro. It may have lasted more than 10 seconds. I had time to walk to the window to see if there was some monsterous truck on Battleground Road. There was a little wind blowing, and I heard only a faint rumble, which I think was the building shaking. One patient asked if it was an earthquake and I replied that I couldn't think of anything else that it could be. Then it was over.

It wasn't frightening. I was standing, but the shaking wasn't strong enough to make me feel unballanced. It didn't make the I.V. poles sway. I am more concerned about huricane Irene. I was a paramedic in Surry County when huricane Hugo came through (years ago), and that caused a lot of damage there.

Everybody be safe.
