"Many families are looking to take inexpensive vacations near to home. We want to encourage Americans to get into the great outdoors to visit our national parks where they can enjoy our nation’s rich natural, cultural and historical heritage. And while they do that, they’ll be providing a boast to our economy. Therefore I’ve ordered the National Park Service to waive entrance fees in national parks on three weekends this summer. Just about every American can make it into one of our national parks. I hope that Americans will take advantage of this great opportunity."
