@ai6yr We lived in a *very* cold house in Boulder CO back in the day. One of those group houses "on the hill" (college section of town).
It was a great day when we set up the dome tent in our bedroom and heated it with an incandescent lamp. Plus we put stick-on glow-in-the-dark stars and planets on the inside of the tent so we got a light show every night after we turned out the light.
