For an outdoor enthusiast like myself, the allure of a National Park is hard to resist. The National Park Service preserves natural, cultural, and historical sites all across the United States. Some of the most breathtaking landscapes are within these park boundaries. Thankfully, the National Park Service has taken it upon themselves to offer a FREE lifetime pass for US Citizens that have a permanent disability. It allows you to be admitted for FREE to more than 2,000 federal recreation sites.
