This upcoming Sunday is the 2012 NBA All-Star game in Orlando, FL. While the game isn't until Sunday, the weekend's festivities actually started yesterday at NBA All-Star Jam Session. Jam Session is just down the road from the Amway Center at the Orange County Convention Center. There are skills competitions for fans, free autograph signings and even a celebrity game. If you get a chance to attend Jam Session, make sure you stop by the Mitchell & Ness section at the NBA Shop.
