Apparently Tony Hawk is tweeting out clues as to where he is traveling around to on his nationwide tour. He surprised those in Columbia, Missouri at Cosmo Park Saturday afternoon for a free taste of skating flare. Fans found out only Friday that Hawk would be at the park. Each location he attends is unknown to fans until days before he shows up. Hawk said he has more than 1.7 million twitter followers. It's a helpful public relations tool that's enabled Hawk to reach new heights with his fans. Philadelphia is the next stop on Hawk's tweets from the road tour.
