There’s one closing that we neglected to mention in last week’s roundup of summer comings and goings at Westfield Montgomery Mall. The Sears Auto Center shut its doors at the beginning of August, four months after the property was purchased by mall owner Westfield Corp. Westfield also bought the nearby Sears department store, which continues to operate as usual under a lease-back agreement with the troubled retailer. Sears spokesman Howard Riefs says that’s the way things will stay for the foreseeable future. “The store will continue to remain open,” he says. We say: Don’t bet on it.
