Two new play pods along a trail loop at River Legacy Parks offer a place for moms and dads to rest while their kids have a ball.The pods, a concept called a “play trail,” are along a trail near the park’s main playground area. As families explore the trail, they encounter the nature-themed pods, which promote physical activity and fun, as well as signage with fun facts and activities related to the theme. On River Legacy’s play trail, kids can climb a frog, seesaw on a dragonfly’s wings, spin on a turtle’s shell and more.UnitedHealthcare provided funding for the project as part of its employee-driven “Do Good. Live Well” initiative, whose mission is to prevent hunger and obesity, inspire service and encourage volunteerism. Arlington native Katie Schell, who recently moved back to the city after living in Las Vegas, said she thought the additions improved the park’s overall appeal.“You want to go to a playground that has updated stuff that the kids enjoy,” said Schell, who can remember playing at the park as a child. “Even though they technically enjoy everything, it’s good for the parents to enjoy it, too.”The pods will give children the chance to run out their energy in a fun way while also keeping them and their families active, she said.Funding for the pods were made possible through CBS EcoMedia WellnessAd program, which promotes social change through environmental projects nationwide.
