Children play Wednesday in water spraying at SplashMor, an interactive exhibit at the Children’s Museum of Richmond on West Broad Street. The young visitors from the Piedmont Family YMCA in Charlottesville had an early start on the Memorial Day holiday, which is considered the unofficial start of summer. The holiday, to be celebrated Monday, May 25, honors America’s war dead. With sunny skies forecast, the holiday also will feature cookouts, swim parties and other fun outdoor activities
