I had a rather terrifying experience with my Edge and snow. I live in Saskatchewan, Canada, and about a month ago we got a very nasty snow storm. Now generally, to get home from the south end of the city i take a back grid road because it's much faster. Generally it is plowed, and even if it isn't the edge has no problems tackling a couple cm of snow.
Well, I was driving down the road and notice the train ahead was stopped on the tracks not moving. So I figured I would go down the side road, and take the next road up to beat the train. I pulled up to the road, and was completely unplowed. Someone had already driven through it, and it looked like it was about 2-3 cm deep. So I went for it... well I was wrong. Turns out their 16" deep tracks and had been mostly filled with snow, and I was trying to plow through it in my Edge. Turned the traction control off, foot to the floor, and somehow I made it all the way to the train tracks. I was in the middle of nowhere, so calling for help would've been impossible. Of course, I get to the top of the little incline where the tracks are, and see that there is no road afterwards, just snow. Didn't want to risk it, so i turned around and gunned it back through my tracks, and made it all the way back. I couldn't believe that my edge had just done that, as i'm sure some trucks would've gotten stuck!
As I finally hit the gravel on the road again, I noticed a tiny little "Road Closed" sign, half covered with snow.
An experience for sure.
