Travelling by car along mountain roads in winter time

I do lot travelling by car along mountain roads here to reach out to the reindeer herding occations. In winter time we use to collect all our reindeers and count them for to send the numbers to the government. Since some years we must also feed our reindeers out to the mountains since we have almost no whitemoss left for the reindeers to eat. The climate change has made it hard for the reindeers to survive on its own. There is more worthless grass growing on the mountains and that competite out the important reindeer feed, the whitemoss. Because of 0.4 degree warmer temperature we have got 11 new herbs and grass sorts growing up with longer roots than the whitemoss has. That kills the whitemoss.However, here is a couple of pictures a january night that says some about how much snow it can be here near the border between Sweden and Norway.
