Ok, wait a minute now. So you walk in the snow to the door, knock and no answer. You and your acomplance walk around back in the snow to take some pictures. Then you all walk back through the snow to your car and drive away, in the snow.
I live in the south so we don't get a lot of experience in dealing with snow. But I am pretty sure if someone goes walking around in snow they will leave foot prints. I can just imagine this homeowner, coming home, seeing fresh tire marks in his drive way, then spotting two sets of footprints in the snow to his front door. Then strangely they walk around his house and up his back deck. What must be going through his mind as he sees snowy footprints walking all around his deck, he must have called the police thinking he had a stalker or peeping Tom. But then he remembers, it just his purple kettle they all come to see. I mean blue -ish.
