The Congress Park School PTO raised about $13,500 last week for flex seating in classrooms and other initiatives during its “Back to the Future”-themed walkathon on Oct. 5, which was held in the school gym because of rainy weather. In addition to kids doing laps around the gym, Principal James Robinette dressed up as “Doc” from the 1985 film while Rich Weissensel and Hugo Kammerer supplied a pair of DeLoreans to complete the scene.
