"Find Your Park", 4/18 through 4/26, all National Parks had a free weekend. They do this several times throughout the year. Be sure to check with your area National Park or their "website". "Shenandoah National Park" is part of the Skyline Drive, in Virginia.
Virginia has lots of National Parks (& state parks.), I bet your state does 2. We went on 4/19, Sunday, an overcast day, on the cool side & it did rain a bit. Lots of hiking is available.
"Eddie, #80" one of our Serta Sheep had a real ball. He says 2 hooves up on Shenandoah National Park!!! Beth ( :
