The Department shall establish a Disabled Veteran’s Passport that entitles the bearer to: (i) enter state parks in the Commonwealth without the payment of a parking or admission fee and (ii) receive a 50 percent discount on camping and swimming fees, picnic shelter rentals, and other Department-provided equipment rentals. The passport shall be issued upon request to a veteran of the armed forces of the United States with a letter from the U.S. Department of Veterans Affairs, or from the military service that discharged the veteran, certifying that such veteran has a service-connected disability rating of 100 percent. The passport shall be valid for as long as the determination of the 100 percent service-connected disability by the U.S. Department of Veterans Affairs remains in effect.
