Hell, as far as I know, Houston has no zoning laws whatsoever. Anything could wind up built next to anything else. This was especially true, it seemed, for titty bars and pawn shops, which were the most common sight for me when driving through that godforsaken American version of Hong Kong.
Mmm, the smell of fresh exploded oil pipeline in the morning...
All things considered, the portrait mode captured the smoke plume pretty well.
But in all serious, seeing those emergency vehicles, then not seeing them after the explosion made me :(, especially in light of the news reports saying that almost every firefighter and EMT who was on the scene was killed.
