A few years back my wife and I went on a road trip to visit our younger son, Evan, who's finishing his post-doctoral studies at Northwestern University. The trip took us from eastern Washington state to Evanston, Illinois. We left in mid-October, usually a time of year when the fall weather is warm and pleasant. During our trip we were caught in an unseasonably early snowstorm which started as we passed Missoula, Montana, and continued all the way to Chicago.
All told, several feet of snow fell during that trip. The driving was a little slippery at times, but we had our snow tires on and an AWD vehicle, so our traction was sound. We traveled on an interstate Freeway, which was frequently plowed and de-iced.
My wife and I usually share driving duties when we do a lot of car travel. When I sat in the passenger seat, I grabbed my camera and snapped some photos of the scenery. The light was often low because of the cloud cover and snow, but I think the photos tell the story of our trip.
Here's a photo gallery of what we saw, presented in the order the photos were taken while driving from central Montana to Wyoming. It was a winter wonderland in early fall:
We left Montana and now entered eastern Wyoming:
