There IS something going on 3 blocks east.
Sigh...I don't have much hope. Figures they'd film in my neighbourhood and then hide from me :-(
ETA: Checked back, still couldn't find them. We've given up. We're assuming that they were filming Thursday during the day, or Wednesday night, and someone forgot to take down the signs on Commercial. It's either that or the entire Supernatural crew is invisible...because we freakin' COMBED those streets.
