Sure wish I had a dash cam from my days when I used to travel daily over the Great Divide through Eisenhower Tunnel back in the 90's. These sort of things one would witness, almost daily, for a few months of the year. Don't know how I survived! Did have a St Christopher medal, maybe that's how...
Here's a short video going through Eisenhower tunnel. I recommend anyone who is not familiar with the beautiful Rocky Mountains, watch this!
The video was not filmed in the winter, so use your imagination that there's several feet of snow and no visibility... it's real fun!
