We headed out to Pala Raceway to catch a glimpse of Subaru Rally Team USA drivers Travis Pastrana and Dave Mirra hitting their practice grounds. Practice grounds for what, you say? Practice grounds for the X Games 16 in Los Angeles, CA. The Summer X Games events will begin tomorrow morning and run well into Sunday evening. The Rally Car and SuperRally races will take place on Saturday, July 31st. And you'll get a dose of Moto every day except Saturday, which will be fulfilled with some hot races by the caged-rally machines. Make sure to come out and cheer on the boys of Rally and Moto as they take on the legendary X Games competitions.
