Mainers will lace up their sneakers this weekend to help those with hearing loss. It’s the University of Maine Delta Zeta Sorority Alumni Chapter’s third annual Hike for Hearing. Funds raised go to the Warren Center in Bangor. The facility provides speech and audiology services for adults and kids. The hike starts Saturday afternoon at 2 o’clock at the Orono Land Trust, behind Orono High School. It costs $10 per person or $30 per team of five.
