This just in: "Bomb squad at 135 Post near Kearny now, evacuation in order."
But: it appears no bomb was found. Alas. Also, MTA spokesperson Judson True tells SF Appeal "that service on the 30 Stockton, 45 Union and 9X Bayshore Express has been disrupted in the Post/Kearny area since 1:02."
We'll update as soon as we know more.
Update: Two bomb scares; no bombs. Pft. Also, and most jarring of all, police and firefighters also evacuated Gump's at 135 Post Street. Can you imagine a San Francisco with no Gump's? Horrifying.
