Winter!

   Today marks the beginning of the winter of 2008-2009 on the Speed
   Gibson calendar, given that we haven't reached 40 degrees the past
   seven days.
   So, fall lasted just 49 days, exactly 7 weeks. That's a lot shorter
   than the published 13 weeks or so. If spring arrives on April 20th
   like this year, then winter will take up the slack at 21 weeks. Those
   of you who know that d(sin t)/dt = cos t understand that spring and
   fall are shorter periods of faster transitions. Summer, even here,
   went 16 weeks on my calendar.
