Shortly before Rick McDougall parks his United States Postal Service truck at the intersection of Lake Avenue and Forest Street, the snow begins to fall. It collects on the cold ground and on the high drifts that have nestled in yards. McDougall begins to make his way along his neighborhood route, trudging along the narrowly shoveled paths on the sidewalk. He seems unphased by the weather, even a little chipper, despite the negative seven degree wind chill.
