OSU’s fourth annual Wooster Campus Scarlet, Gray, and Green Fair takes place today (4/19) at OARDC. Wind power info? Got it. Solar? Check. A custom-built plug-in Toyota Prius that gets the equivalent of more than 100 mpg? That too. In all, some 60 or so displays, exhibits, vendors, and demonstrations, all featuring some aspect of sustainability, will be in OARDC’s Fisher Auditorium and under big tents nearby. Last year some 2,000 people attended. 11 a.m.-7 p.m., free admission. (Note: OSU President Gee was to have given the keynote talk but had to cancel due to unfortunate circumstances.)
