"Tommy grew up in Estes, but you notice that so many families and so many kids just don't go into the the National Park," says Becca Caldwell. While Rocky Mountain National Park is just a short drive from Estes Park, CO., Becca found parents gravitated to the local playground and coffee shops for playdates. "Why aren't we going out on the trails and letting the kids run loose? How can we change that for my sons's generation?" she asked. It's a question that many experts have been asking too. 

Today, for the fourth episode of our Mileposts series, we hike with the Little Explorers in Rocky Mountain National Park, and see how Becca's simple act is forming a community of kids and parents out on the trails.
