Yesterday threshold, today Dark Side begins
Yesterday was threshold day for Denver. Sunrise 6:51 am, SunSet 6:51 pm. 12 hours and 12 hours.
It will be awhile before the Bright side returns.
You can check your Dark Side exposure by looking at:
-- check lights
-- check batteries
-- check planned clothing for different wind chills
-- check tires
Doh, I missed it. Yesterday was the day for DC too.
 just out of curiousity, does anyone know if that's a hemisphere thing? I.E. the entire northern hemisphere passed the threshold yesterday?
