And for those of you commuting by car today, don't you you spared the air? A truck overturned right at the 92/101 S interchange (those ramps are pretty steeply banked) around 4 a.m. this morning, and they didn't get the ramp reopened until 8.

On the other hand, be careful sparing the air today too -- a man hit by a T-Third is the fourth MUNI-related pedestrian death accident in two weeks (two of which were fatal).
