Happy Birthday America!  The SMX Insiders are giving you a star-spangled preview of the biggest Motocross race in America.

Jason Weigandt and Jason Thomas preview the unpredictable 250 class, whether Deegan is really getting closer to the Lawrence brothers, and who is rising and falling in SMX Points as the playoffs approach. All this plus Jeremy Martin in the Big Interview, and Dr. McGinley talking about the road back for Chase Sexton in the SMX Medical update.
