Answered call showing 'Napa' origin, but when no one spoke up I disconnected. Checking on it here, I see it's yet another wave of the fake solar energy for qualifying homeowners. We started getting those over a year ago. If they do start into their pitch we tell them we're not homeowners (true), they're a scam (also true) and don't call again (not respected). Would be kind of fun to string them along with fictional information, though...
These scammers have several 707 area code numbers. One time the calls appear to be coming from Sonoma, then Benicia, St Helena, Calistoga and this one supposedly from Lake County.
No more Robo gets the new number and plays whack a mole with them very quickly.
