WASHINGTON - A UPS truck jumped a curb and broke through a concrete barrier, crashing into the Hirshhorn Museum and Sculpture Garden on the National Mall Monday night. The truck loaded with packages sheered off an ornamental light pole and plowed through a row of flower pots. It went into the plate-glass window of the museum's lobby about 8:30 p.m. The window, which is punctured at its base, is a spider web of cracks.
