If you're looking for something to do with your kids this summer, take them on a scavenger hunt.There are a few that are already set up, and WGAL News 8's Matt Barcaro takes you to one of them as part of our "Explore Outdoors" series.Julie York and her kids, Millie and Liam, have turned into quite the hikers. It's a pastime they picked up when they moved to York County from out of state and started exploring their new backyard.Thanks to a program they stumbled upon in their library, they don't have to plan any of the trips they take."We travel up to an hour away sometimes to get to some of these hikes, so it's taken us to new places that we probably wouldn't have found on our own," York said.The York family is one of thousands of families taking part in the Get Outdoors York program, which is run through York County Libraries.At their library, kids can pick up a trail guide with clues inside that will take them to dozens of county and state parks and lead them to hidden wooden posts.They can enter the code found on each post into an app for a chance to win prizes."One of the things that's nice about it is we introduce families to all the different park systems around the county," said Sandy Gladfelter, a WellSpan Health educator.Gladfelter helps map out the trails each year and writes the clues, which kids are encouraged to practice reading themselves."We know during the summer kids sort of stop that school process, so this is an opportunity for them just to be able to continue their reading and further that along and then learn some really cool stuff," Gladfelter said.This year, each hidden post features a design of a different animal's tail, with the goal of making a rubbing of all 30 of them.Gladfelter said any way to get kids outside is important."And it's not just the kids. It's their parents and it's their families and it's their caregivers and supporters," she said.And just like with the Yorks, tracking down the tails can become a family affair."So, it makes me feel good as a parent that my kids are getting outside. They love being outside. They love doing this program," York said.The Get Outdoors program is also offered in Lancaster, Lebanon, Adams and Franklin counties through Aug. 22.
