The sun came up, and we emerged from Four B’s to discover a warm chinook blowing in. Already the eaves were weeping, icicles thinning on trees and telephone wires. This is what Montana does in midwinter: clears off and gets bitter cold, and then suddenly it’s as warm and exhilarating as Easter morning. Don’t believe it for a minute, you tell yourself as the streets turn into trout streams, but the sheer pleasure of the feeling makes a fool of you. You forget your scarf and mittens on a hook behind the door. You know it’s still winter, but that’s just what you know; the chinook is what you believe in.
