Fire department called at 10:58a PDT, asking to check out a box at the South Mid-Station, so I said "sure, no problem." After speaking with Robert, he suggests that when they get a glitch in their alarm system, they have to send someone out to confirm its not a fire, which we suspect is the case -- no fire (confirmed by corner station camera), glitch in the system, routine check. Will post if we hear anything further/otherwise.
