I think it was Dr. Phil who said nothing builds family unity like kicking another family's ass in a tricycle race. Come out to the park and celebrate your family pride at the Carolina Hoopfest & Family Challenge 2007. See if dad can really dunk like he swears he used to in high school, find out how good mom can work her hips with a hula hoop and then argue in the car on the way home after losing in family trivia because you forgot Timmy's favorite color. Free food, free health screenings and a chance to see the police beat up on firefighters (instead of you). Ahh, togetherness. 9 a.m.-6 p.m. Free. Camp Green Basketball Complex, 1221 Alleghany St. 704-759-9538.
