It's a clear, sunny weekday in May. A man wearing a hardhat shaped like a Stetson materializes from a construction site. His name is Rodney Freeman, and he is a member of The Jewish Federation of Greater Los Angeles' Real Estate & Construction Division. He is also on the committee supervising the biggest enterprise ever undertaken by L.A.'s Jewish Federation - the refurbishing of the nonprofit organization's 6505 Wilshire Blvd. headquarters.
