I remember my grandmother who lived in Kenosha, Wis. taking our sheets from off the beds in the summer and putting them into the refrigerator. Just before bedtime she would put them back on and tell us to get into bed. "you will be nice and cool." She would say. We may have been nice and cool, and clammy for about 10 minutes, but we also smelled like onions, carrots and left over cake with rasberry filling. (She was Danish)and did't throw a thing out. What fond memories from childhood. I thought everyone slept in sheets that had been cooled it the fridge. Abcomatic
