Received a call on 9/18/14 at 7:07 p.m.; displayed on Caller ID as: "Big Rock IL", so we didn't answer, and just let our answering machine record the call.  It was a political robo-call, asking whether or not we were registered voters and, if so, whether or not we are planning to vote in the next election (or something along those lines; I didn't give the message my full attention, and then I immediately erased it!).  Hoping that this was a one-shot deal, and that they won't keep calling until someone answers...because we will NEVER answer calls like this!
