In the interests of prompt, rather than accurate, news: it looks like a garage (or other outbuilding) on the south side of the 500 block of Lincoln burned this afternoon. Around 3:50PM I heard a loud thump; when I went outside to look around, I could see black smoke boiling up into the sky from a couple blocks away.
According to the police officer who evacuating people from their houses across the alley, an electrical line fell into someone's back yard and started a fire. I could see the fallen wire easily, although cause and effect aren't always clear.
It seems like the fire department was on it pretty quickly -- I saw at least five fire engines along with plenty of police as well. Hopefully there was limited damage (better a garage than a house!).
The police quite wisely kept all of us lookie-lous off of the actual block on Lincoln with all of the excitement, so I had to go back to work writing software. I'm probably better off leaving the color commentary to David Allen, anyway... :-)
