My hangar beer fridge is the Sanyo "college" fridge I bought in 1978, it's a bit battered but it still works. I do unplug it for the winter.
Aviation related refrigerator story: My first dorm fridge belonged to one of my best friends, Kevin Buerlein, at Parks College. His dad was a TWA captain. Kevin learned to fly at Parks in his freshman year, as I had done a year earlier. He went home to NJ for the summer and I stayed for the summer semester, so he left his fridge with me for the summer, during which he crashed and died with his little sister in a rented 150 off the NJ shore. From the accident report, it sounded like he botched a wingover at low altitude, a young man showing off. His mother told me to keep the fridge so I did until I left the school, at which point it only seemed right to donate it to another of his friends with the request that they pass it on to another student when they in turn left, and I bought a new one, the same one I still have, to take to my new school.
