At ground level, the patted-down snow doesn't look like much. But from the hospital windows above, the messages are quite clear. The latest are the words "love" and "believe," along with a peace symbol. Each time there's fresh snow, there's a new message.
Nurse Mary Habiger has seen a man and woman in snow shoes stamping out the messages. She says the mystery man and woman seem well organized and plan their messages in advance.
Habiger tells a local television station that there are lots of family lounges in the hospital that face the river. So even if a patient's room doesn't overlook the river, they can view the messages from there.
