Caller ID showed a phone number issued to a local public elementary school.   At 10:20am on Sunday robot Elizabeth called from the prize center.  Usual spiel; "You stayed at our resort, we want to give you a free vacation in Orlando and the Bahamas."  I asked Elizabeth- "Who is buried in Grant's Tomb?"  She didn't skip a beat.  I asked, "What time is it?"  No response.  At the end of her robotic [presentation I asked Elizabeth if she were a robot.  No response.  Then she asked me if I had any questions.  "Who is buried in Grant's Tomb?"  No response.  Again I asked "Who is buried in Grant's Tomb?"  dead air, then disconnect.  These criminals use local numbers to convince us to pick up.  Not good
