It isn't snow, these are bubbles. This big fountain is at a nearby subdivision - and it's often a target of vandals who pour bubble soap into it. I figure this is because the subdivision is near a high school. Maybe it's not fair to blame high schoolers, but they did get caught once. The bubbles had faded to a soap scum by the afternoon. The ducks who live here have to find new digs for a few days when this happens.
