So sorry to hear about your incident. You did the right thing in not answering the door. Who knows what those guys were up to but it wasn't good. I think you are right-they may have been casing the place out during the day. I'm sure you will have a sleepless night but hope you get some rest when daylight comes. I have had 2 scary times like you have and know your fear. Take care and let us all know if the 911 guy calls-hopefully to let you know the police have caught them.
