Just like DC

First I though, an explosion? Then I read the article and I think so what? Happens all the time around here. Well, actually it hasn't happened in a while, I think.

(KCBS) - An explosion shook office buildings near Post and Kearny streets in downtown San Francisco shortly before ten o'clock Friday morning.
San Francisco fire department captain Pete Howes told KCBS a man hole cover in front of the Ralph Lauren store at the corner of Post and Kearny appeared to have exploded, although the exact cause of the blast is under investigation.

Is there any significance that it happened in front of a Ralph Lauren store?
