ahhh...and as an aside.
TIP: I heat up an 8" cast iron skillet on my stove, and rub it around under the blankets before jumping into bed...a cheap alternative to an electric blanket for warming up the bed during these cold winter nights.
Something that works much better than an electric blanket, is an electric mattress pad. They heat from the bottom up, and depending on the size have heat controls for each person just like blankets. It could be used on the hook just to get the bed warm, then turn it off before you get in to save on electricity. We have one at home, and I wouldn't want to do without one if I could help it.
