In the old Southern town of Lexington, Virginia, letters to the editor stretch from last week's News Gazette back to 1804. Student researchers at Washington and Lee University sought out as many of those letters as they could, indexing more than 8,000 and transcribing about 1,400. This rich material was turned into a play that premiered at the Theater at Lime Kiln. With hundreds more published here, along with the original script, the voices of the Valley speak again, glints of gold out of the creek bed of Time.
