I was working on some code in my apartment, was thinking about going out, and looked outside and the sky was black. At first I thought it was another thunderstorm. I got drenched this morning. But then when I got up to look I saw it was a fire. I got out my camera and took a picture, uploaded it to Flickr, and tweeted a link to the photo.
Then I noticed that other people were posting pictures of the fire from all different points of view. Within a few minutes we knew the exact location. Now about 1/2 hour later, I can see that the fire is out.
