Blizzard

We followed the herd, sometimes veering slightly right or left so the reindeer wouldn't close into a circle. Once they form a circle, they're hard to get moving again. At some point the fences on either side gave way, and we came out onto the open expanse of a lake, ringed by low fir trees. This is where the reindeer were to spend the night. In the morning, once the blizzard died down, they would be driven farther, into the mountains.
