TUSCALOOSA, Ala. (WIAT) - After a grueling season of long practices and dozens of sacrifices, high school students and their fans have arrived in Tuscaloosa for the biggest game of the season.  For some students, it will also be the biggest game of their lives.  While some participants plan to continue with their cheerleading, marching band, or football throughout their college careers; for others this is the end of the road.  They are all perfoming in front of the largest audience of their football careers and for many, at the largest venue inside of Bryant-Denny Stadium.  For the 35 thousand athletes, performers, and fans this will be the opportunity of a life time.
