More than three decades ago, tiny blobs of gelatinous goo of unknown origin rained down on the small Grays Harbor community and captured national headlines.

The cause of the strange phenomenon, and even what the blobs were made of -- remains an enigma. It was even the subject of an episode of the TV show Unsolved Mysteries. (Watch the episode here.)

No one knows what they were. But last month they returned. 

Guests:

• Alli McCrite
• Tom Paulson, former reporter for the Seattle P-I
