Big badda boom ... scary stuff ... the 401 (North America's busiest highway) is still closed.I can't ever think of a time when that happened for this length of time.
Last big local gas explosion, which was WAAAY smaller than this, was about 3 blocks away from me and shook the house nicely. I can't imagine what this one was like (and, nope, it didn't wake me up, but I was sleeping off my 6YO's birthday party, so ...).
