The way buildings are designed changes based on how they need to work with their environment. Here in Oklahoma, Air conditioning is far more important most of the year than heat is. Since cold air sinks, you need the household vents on the ceiling so that all of the cold air doesn’t stay settled on the floor in the summer. In a colder climate like Wyoming, it’s the opposite. You put the vents on the floor so that the hot air doesn’t stay stuck on the ceiling in the wintertime. This feature actually saved my life once.
It was back when I lived here.

Gosh I don’t miss that place.
Any-who, like I was saying, Wyoming is cold. In the winter you can feel the inside of your nose start to freeze after just a couple of minutes.
As cold as it is in the winter though, the other kids on the bus were still obnoxious so one day in the winter I decided to walk home instead of dealing with the loud and noisy bus. I was walking through the park, and they’d put up secondary fencing to catch the blowing snow. The snow drifts that piled up there were easily chest high to a grade schooler, and usually stiff and crunchy on the top. There was snow blowing around, I was pulling my feet up almost knee high for every step I took, and probably ten minutes in puffing for breath, nose numb, cold and tired after school… I was feeling pretty tired. I just wanted to take a short rest and close my eyes for a few minutes…
And I did. I lay down on a snow drift and closed my eyes. I was cold. I was so cold. And tired. But…
It would just be so much nicer to take my nap at home. I’d grab my fluffiest blanket and a cup of cocoa and wrap it over the warm air piped straight from the floor vent and nest up in a tiny warm cocoon. Yeah. It would be nicer to curl up around the floor vent.
So I opened my eyes. I picked myself up from the snow. I finished my slog home.The floor vent was a much nicer place for my nap. The design features of my old house saved my life.
