Hot-Tubbing at 3F

Intrepid experimenter tries hot-tubbing when the air temperature was a whopping three degrees Fahrenheit.

Advantages	Disadvantages
Getting warm	Getting to it, naked, while my skin freezes off
Beautiful moonlit night	Billows of water vapor
Soaking wrist in warm jets	Freezing nose hairs with each breath
Being exothermic so returning to house wasn't cold	Literally freezing my fingers to the door

Could have been worse. Could have been below 0F.
