CHARLESTON, W.Va. -- The Clay Center's 2013 spring season kicks off Sunday with the return of the Walnut Street Theatre, the oldest theater in America. The Philadelphia company, which marked its 200th anniversary in 2009, will perform Jules Verne's "Around the World in 80 Days."Five actors will take the audience across the globe in a fast-paced adventure full of secret plots, a damsel in distress and narrow escapes as Phileas Fogg and his trusted valet, Passepartout, attempt to prove if such a journey is even possible.
