fire on saint marks?

there's a ton of black smoke in the air... from my window, it looks like it's down on saint marks and classon? anyone have any info?

I saw it just as it really got going. Well, saw it from a block away at the Park Place shuttle station. Couldn't see what was burning, but it was a pretty big fire- I could see the flames and the rolling black smoke. I only stuck around long enough to call 911- the fire was close to the tracks and the shuttle conductor didn't want to risk it, so I had to get to walkin'...
