Try spending 6 weeks in Yellowknife (North West Territories, 60 miles inside the Arctic Circle) in the dead of winter, with daily average temperatures of 60 degrees below zero.
I did. Many years ago with a band. No one in the band wanted to go, except me. My rationale was, When will we ever get a chance again in our lives to go to Yellowknife - at someone else's expense? And the money was good and we needed the work. So we went. Took 3 separate planes to get us there, and we landed on a snow-covered runway. We literally got off the plane and stepped into snow. Several cabs met us, and took us to the hotel. We caught a break here, as the hotel was new and fairly nice, and it was built primarily for government people so that when they came to Yellowknife they'd have decent place to stay. We played mostly to Native Indians and the staff. I think they were so grateful just to have a decent band, they didn't care what we played....they just stayed and drank, and a while we became incidental to them.
In the winter in Yellowknife, the sun rises at about 7:00 am and sets around 3:00 pm. We were party animals back then and often didn't crash till 5 or 6 in the morning, awaking at around 4:00 in the afternoon (yes we were good in bed -often sleeping for 12 hours!!)....but the bizarre thing was, that for weeks we never saw daylight, and it was quite disorienting.. Apparently in the summer there, you can play golf at 2:00 in the morning.
Not exactly a horror story, but it was like being in the Twilight Zone.
