When I wrote about my gambling journey over Donner Summit last week, many of our readers from colder climes expressed puzzlement over the CHP's tire chain requirements on I-80 under not-very-snowy conditions. What's the deal here?

Since the first BumperCam, last summer, I've been experimenting with timelapse cameras. We've seen timelapses of LeMons BS Inspections at Nelson Ledges, MSR Houston, and Thunderhill, not to mention the Alameda to Los Angeles In 90 Seconds video.
