1 - Head to the Big Butler Fair
The Big Butler Fair roars back into action with nine days of festivities, running from July 2-10, including a big fireworks night on July 4th. High octane events include the School Bus Demolition, Antique Tractor Pull and Bull Ride Mania. Carnival rides and games compete with attention on the midway. Farm animals are a big draw with sheep, draft horses, chickens and cows on display. Smaller kids will find more interest in the 4-H Club’s petting zoo and the Parakeet Encounter Aviary. Find the complete schedule here. Tickets start at $8, free for kids 6 and younger.
2 - Check out the history of women’s athleticwear
Fashion history always intrigues, adding a personal context to the flat chronicle of events. A new exhibit opening July 3 at the Frick Pittsburgh, Sporting Fashion: Outdoor Girls 1800 to 1960 adds the element of women’s athletic wear from the turn of the 19th century to the mid-20th century. Young girls and teens will be fascinated by 64 fully accessorized outfits, which beg the question: “How did they move in those things?” The exhibition includes outfits worn for activities from swimming and cycling to ice skating and tennis. Young female athletes will appreciate the evolution of the modern sportswoman alongside the progression of their clothing. Tickets are $8 for ages 6-16, $13 for students and seniors, $15 for adults and free for ages 5 and younger.
