Sports Authority, which filed for Chapter 11 bankruptcy earlier this month, has changed its plans for Maryland since our last report. The Gaithersburg store near Lakeforest Mall is now slated for closure, along with three other Sports Authority stores across the state. The Rockville store at Montrose Crossing is safe for now. Nationally, Sports Authority is laying off some 3,400 people and closing about one third of its 464 stores.
