The annual “Secrets of Allentown” tour will be held this Saturday (Sept. 16). The tour will include several houses such as the Birge Mansion on Symphony Circle, where the tour will begin, and the Wilcox mansion on Delaware Ave., where president Theodore Roosevelt was inaugurated. Guests will guide themselves through the homes, viewing them for as long as they wish and in whatever order they choose. A trolley will be available for those who need it, stopping at selected homes. The houses will be open to view from 11am-5pm, and there will be a free wine tasting at the Birge from 12-4pm. Call the Allentown Association at 881-1024 for advance tickets.
