If you have an entry and things get broken or stolen you will think twice about " it can be replaced" B and E is a personal violation thank you will NEVER forget. Trust me. I have an alarm system and the next door neighbor does a daily walk-thru because I do not shut off the heat. Turn it down to 60. Found that wallpaper seams opened at 50. Water off at main, waterheater turned to pilot, indoor/outdoor thermo stuck into freezer so he does not have to open door to check temp. Another neighbor mows or shovels. Still I don't like leaving. I see a twind-a-min in the future.
