For many, summer means vacation time and leaving home for relaxing or exciting ports of call. But when you're off on a beach far, far away or riding an elephant in exotic Bombay, it's the wrong time to think and wonder: "Did I unplug the iron?" If you're planning a trip and something to do, be sure your home is vacation-ready too. First, there's obvious stuff like halting mail and newspaper deliveries or setting timers to turn on lights and a radio. Let neighbors and the alarm company know you'll be gone. In the heat of packing and getting under way, it's easy to forget things if you don't have a check list. "Things to do" should include avoiding any potential household problems by unplugging appliances and resetting thermostats to save energy while you're gone. Do a full house survey and write everything down. The next time you travel, use it again. And that's the On The House tip for today.
