DELRAY BEACH – This weekend will be the summer’s last hurrah for hundreds of area kids and parents as they head back to school. From a teen dance to a car show to the city’s largest garage sale, there are enough activities planned in one venue for residents of all ages over the three-day event. “We will have something that appeals to every segment of our community,” said Robert Dodd, program manager for the Knights of Pythagoras Mentoring Network, one of the event’s sponsors. “This will not be a white festival or a black festival. It will be a three-day festival for the entire All-America City.”
