08Editor's notes
What the numbers don't tell you
December is cool, with afternoons around 14 °C, and the National Finals Rodeo brings cowboy hats to the Strip for the first two weeks, with country concerts in every arena. Then a quiet, cheap run-up to Christmas, which is one of the slowest weeks of the year, before New Year's Eve, the most expensive night of the year, when the Strip closes to traffic and fireworks launch from the resort rooftops at midnight.
Pools are largely closed; the Bellagio Conservatory and the resort decorations are the draw. Rain falls on about three days, and snow is a rare event that makes the local news. Nights drop near freezing. Shows run extra performances between Christmas and New Year. For the cheapest week of the year, the days after New Year's Day follow in January, before CES.
