From Bill's blog:
We're going to visit a bomb shelter. The concept seems funny today, but the Greens were just going to run into the basement and worry about radiation. A few families had bomb shelters right in their yards. In this story, we visit the Crooker family shelter and talk with MEMA officials about the old days and what we do today if there is a disaster.
Here's a link to Maine Emergency Management's website.
