On their way out of Miles City on their fourth day, they passed a city park where Pirsig remembered  having slept one night on his way to Bozeman. Then they followed the Yellowstone Valley across Montana. At Laurel in sight of the mountains, they stopped for the night. Coming down off the snow, the evening breeze was cool. They felt the presence of the mountains and Pirsig felt happy but a little sad too. "Sometimes it’s a little better to travel than to arrive."
