Snow with sprinkles
For weeks, the now-crusty surface of a persistent snowpack has collected anything dropping from trees -- or from animals.
The snow also provides high-contrast evidence that some dog owners fail to clean up after their pets.
Feces that are not disposed of attract and provide a nutritional bonanza for rats, which feed on the waste.
