Pierre André Senizergues, founder and CEO of Sole Technology, hugs Dan Johnson during the etnies Skatepark of Lake Forest's attempt to set a world record for the largest lesson ever held Thursday evening. The Pediatric Cancer Research Foundation and Team Thomas, a community created in support of eight year-old Thomas Johnson to raise money for pediatric cancer research, will benefit from any donations made during the event. Johnson died from a rare cancer in 2010.
