The Indiana Worlds Skating Academy has agreed to a 9-month lease extension for its space at Pan Am Plaza. The organization will remain downtown at least until April 2008, said Academy Executive Director Pam Robinson. The group was told in October 2006 that it would have to move to make way for a new convention hotel, but the city chose another plan instead. The Academy still is eyeing a move to the State Fairgrounds. The General Assembly has allocated $4 million, half the estimated cost for new rinks. What should be done with the old rinks if the Academy moves?
