We have a pellet stove that heats the majority of our house and keeps things roasty-toasty warm.
My New England-bred husband doesn't believe in artificially warming the house until the interior dips into the low 60s. My own California upbringing says, "anything under 72 degress deserves the heat on." Yes, yes...our heating bill is generally astronomical.
And according to how my kids have been dressing themselves while indoors (i.e., Griffin's muscle tee this past weekend), perhaps I'm keeping it a little too warm.
Even though there's no such thing as "too warm" in my book. I love muscle tees.
