I have call display, and if it is long distance and not somebody I know, I don't answer. i figure if it is very important they will leave me a message. This number calls all the time and today I was sitting beside the phone and answered just to see who the heck it was.  Wow!  Hubby won a 'free' trip to Disney. He said my husband had filled out a ballot. Ya, right. Some sort of scam I assume. I told him to not bother calling back.
