As for the most the most popular extracurricular activities go, I would say the band, basketball, and football would almost unanimously win. Band is popular in the sense of there are a ton of people involved in it, while basketball is popular not for the numbers in it, but the success of the program. Last year Park Hill South placed 2nd at state in Missouri. Football is popular as it is in just about every high school I'm assuming - the atmosphere of those Friday Night Lights is just too good to beat. The extracurricular activities I would recommend, would be really any, as long as it either teaches you something along the way, or benefits you physically, mentally, and emotionally.
