The beginning of two days of crappy weather: on the west side of the pass going through Vail, Colorado. Before I was done, I'd see 4 inches of snow on a three lane interstate, 17-degree low, and a 15-mph top speed for 3 hours on the same interstate, a half-hour ESP workout (the light was flashing for at least 30 minutes thanks to ice and snow on the road and pulling a trailer up through 7,000-8,000 feet of elevation), and a 30-degree jump in temperature making the inside of all the windows on the tow rig fog instantly at 70 mph.
