It's 1 a.m. and again, I cannot sleep. During these hot, dog days of summer I can barely muster an attempt to lay down my sweaty head on my sweaty bed. Instead, I park myself in a kitchen chair facing off against the portable air conditioner, sinking my teeth into yet another dish of frozen blueberries. Oh, what a glorious day it will be to see this heat wave waving goodbye! When we moved into this place on a beautiful, balmy October day, thoughts of sweltering, sleepless nights in July were about the farthest thing from my mind. As the first rays of summer sun set upon us last July, we deliberated whether to spend $500 on a portable A/C unit or $5,000 on central A/C. Clearly, we made the wrong choice. Because now we are going to have to spring for that $5K unit anyway, and our little cool-air blowing buddy will soon be taking up storage space in the basement. Right next to the freezer full of frozen blueberries.
