BBCWatcher writes: Last election, DailyKos poster craigf suffered four acts of vandalism against his political yard signs. This election he's taking no chances. He illustrates how to rig an Obama yard sign to emit a piercing screech should anybody pilfer or destroy it. This hack requires a wire hangar, fishing line or string, a $5 battery-powered personal alarm from Circuit City (or equivalent), and, of course, duct tape. As an extra-cost option you can add a motion-activated camera to record any sign attackers.
