The Challenger clears the High Level Bridge on the Cuyahoga River en route to the Cleveland Terminal in July 2004. During 2005 the boat was absent on the Detroit-Toledo-Cleveland routes she had traded for nearly 40 seasons . This shortened delivery routine, and an unprece- dented late fit-out, lead to dark speculation about the prospects of her reaching 100 years, at least as a self-propelled vessel.
