Weather station mistaken for bomb

A bomb-squad recently blew up a "suspicious looking box" mounted to a tree near the Lewis-Gale Medical Center in Roanoke, Virgina. Turned out that the "bomb" was actually an amateur weather station placed there by an employee of the Center. From the Roanoke Times:

An employee had placed a putty-like substance around the box to make it weather proof.

The investigation is concluded and no criminal charges will be filed.
