Mile 2518. Back on I-80 in Wyoming, Pete tells me about the Snow-Chi-Minh trail. The story is that the Elk Mountain section of I-80 is so bad in the snow that a detour up to Rock River and back south to Laramie is often a better alternative. We laugh as though this is a ridiculous idea. Near Elk Mountain Storm #5 hits us. There are jackknifed trucks and cars piling up in the divider ditch. Rescue vehicles plow through the snow with sirens screaming. The Snow-Chi-Minh trail would probably have served us well.
