Dozens of volunteers helped pick up trash in Roger A. Reynolds Municipal Park on April 22 as part of Hilliard's observance of Earth Day.

The Hilliard Recreation and Parks Department and Environmental Sustainability Commission organized the fifth annual event.

Hilliard resident Bob Parker and his 4-year-old daughter, Olivia, were among those working outside to clean up the park on the chilly Saturday. They were at the event for the first time.

Parker said Olivia learned about the event at her preschool.

"She wanted to come here and help clean up," he said.

Inside the Hilliard Community Center, 20 organizations gave away items designed to encourage recycling and environmentally friendly practices.

Children enjoying the indoor activities included 4-year-old Clare Marsh and her 2-year-old sister, Violet.

The sisters painted with watercolors made by immersing the cartridges of used markers in jars of water at a station staffed by Norwich Elementary School, one of several schools represented at the event.

"It looked like our biggest turnout yet," said Earth Day organizer Kim Movshin, a member of the Environmental Sustainability Commission.

Movshin, who has organized the event each of its five years, said she tries to plan new events "to draw new people." This year, the Furniture Bank of Central Ohio was a new organization invited to participate.

"I try to have as many collections as possible so people can do a one-stop house cleaning ... and properly dispose (of items)," she said.
