NEW YORK — It may not put a meal on the table for furloughed federal employees, but some U. museums and symphonies are supplying food for the mind in free admission for workers affected by the longest partial federal government shutdown in US history. With the shutdown in its fourth week with no end in sight, cultural institutions from Massachusetts to Oregon are moving to help unpaid federal workers spend some of their otherwise idle hours with loved ones enjoying art, science history or music. Museums in at least 27 states, along with at least 19 orchestras, offered free admission to federal workers who have unpaid time on their hands. Institutions range from The Metropolitan Opera in New York to the San Diego Air & Space Museum, home of the Apollo IX Command Module, which helped pave the way for man to walk on the Moon. Nearly 200 furloughed employees have taken advantage of an offer from the Philadelphia Museum of Art, which waived its admission fee for each furloughed worker plus one guest. — Reuters
