Freezing Pipe Precautions

We've had some very cold weather in my part of the country recently, so I was concerned about my pipes freezing and bursting. A quick search of the internet provided these tips:

• Turn on your faucets to run at a trickle; the pennies spent on the water is less than the cost to fix your pipes;
• Properly insulate unfinished rooms, such as garages and basements, where pipes may be exposed;
• Consider "snap on" insulation or wraps for piping;
• Drain and shut off pipes flowing to outside faucets;
• Seal cracks and holes in outside walls and foundations near water pipes with caulking; Set thermostats at a minimum of 60 degrees Fahrenheit;
• If away frequently, consider the installation of a low-temperature sensor, which activates an alarm if the home temperature falls below a preset level; and
• During extended unoccupied periods, turn off the water supply and ask a trusted individual to check the home on a daily basis for heating system malfunctions and frozen pipes.

I do believe I followed all of the ones that are applicable to my situation. Anyone have others they employ?
