Many are the basketball fans who regret not seeing Michael Jordan in his prime. Don’t make the same mistake twice. You can check out his heir apparent, the colossal LeBron James, who leads the Miami Heat in regular season home games through April 17 at American Airlines Arena in downtown Miami. The Heat, the reigning World Champions, currently have the best record in the NBA’s Eastern Conference and are expected to make the playoffs. The 19,600-seat arena, built with state-of-the-art sound, also hosts major headliners, from U2 to Lady Gaga.
