If you’re feeling the need to walk off some of yesterday’s calories, head out to a local park, refuge, trail or recreation area for some fresh air and exercise. One of our favorite places to #OptOutside is Chesapeake & Ohio National Historical Park. Running 184 miles from West Virginia through Maryland and into Washington, D.C., the towpath and trails of the C&O Canal offer great opportunities to discover historical and natural treasures. From the popular trails around Great Falls to the quiet splendor of the upper sections, it’s a place we’re thankful for. Photo by Patty Ballay (www.sharetheexperience.org).
