Turn of the Century DayAll the old-time mountain fun of 1898 comes but once a year in Roxbury’s celebrated Turn of the Century Day festivities. This Saturday, Sept. 4 the entire family can enjoy vintage baseball, children’s crafts and games, a parade of fashion, vaudeville acrobats, spectacular fireworks at dusk, and as always, plenty of vintage victuals, including grilled sausage sandwiches, chicken barbecue, fruit pies and beer and wine for the grownups.
