Over the next several months, the Friends of the Oklawaha Greenway will host “Oklawaha Greenway Walks and Talks,” a series of educational outings. The second in the series -- on Saturday, August 20, at 10 a.m. -- focuses on the glory of fall wildflowers growing along the Greenway. The program is open to the public at no charge. Meet at Patton Park in the circular pavilion near the basketball courts. The walk will be about 90 minutes, returning to Patton Park. The hike will be held rain or shine.
