I love my electric blanket. What you might find interesting is that I had it before I moved to Iowa. I bought it in San Antonio -- one day several years ago, while walking through Sears, I saw a display of electric blankets. I don't think I had ever seen one in San Antonio, and figured it was a sign that I should buy one. I even used it in Texas, where my house, like most there, was poorly insulated and drafty. (I've always wondered why builders in Texas don't seem to realize that good insulation would help air conditioner efficiency, too.) In San Antonio, though, I rarely turned it higher than 3 on the dial, while 5 or 6 has been the norm this winter.
I grew up in an old, drafty house. The bedroom my sister and I shared was on the north corner and, in my memory at least, I spent every night curled up in a ball under a pile of blankets. I was always cold. Sometime after I left for college -- maybe it was even after I was married -- I came home to find that the entire family had electric blankets. I was amazed and wondered why this solution hadn't been thought of years earlier!
