The largest Snow Plow/Blower/Removal Machines

Here in Frankfurt we dont really have a lot of snow. Sadly most of the time it only rains in the winter. Most people do not like snow here anyways and they are not used to it when driving for example. So whenever it does snow a little. Traffic collapses and everybody gets crazy. As a skiing fan i would love to have a lot of snow, maybe 2 or 3 weeks long during the winter season. So i enjoyed watching this video with large scale plowing Equipment ;-) I guess in some parts of the world you might have too much snow and get tired of it...

The author hid some sort of easteregg in the video, can you tell?
