Also the same from the rest of the crowd here; I picked up the phone, nobody said anything. Probably shouldn't have done that since there's an infamous call out there that can siphon out your information through a phone call. Whether or not that's legit or just a rumor is up for debate.
Just got a call from this number, no voicemail. Seeing so many others from SF posting here today regarding this number, I'm guessing it's probably a pollster or something related to the elections.
