I had to walk to work this morning after a residential building exploded and collapsed on the Upper East Side at 62nd and Madison, near my subway line. The explosion came just as I was heading down the stairs into the 68th Street Station and startled me so much that I dropped my newspaper. The woman in front of me came to a dead stop and said, "THAT did not sound right." I followed her up to the street where we could see a huge plume of black smoke blowing across Lexington Avenue a few blocks away and my very first thought was, "Holy shit! They've blown up Bloomingdale's!", as Bloomie's is just a couple of blocks from the exploded building. Nothing like a terrorism scare to start off the week.
