Which U.S. President made a daring escape from the enemy through Riverbend Park? What does the House at Hidden Pond Nature Center have in common with the White House? Which Commander-in-Chief saved Sully Historic Site from demolition? The answers to these questions and more can be found in this year’s Fairfax County Park Authority Discovery Trail Map – Presidential Edition.

Now in its third year, the free Discovery Trail Map summer fun activity encourages students age 17 and younger to explore 12 distinctive parks and explore their unique features and connections to U.S. Presidents or their administrations. Students who visit eight of the 12 featured sites will receive tickets to more park fun valued at nearly $90 and will be entered into a drawing for one of three bicycles and helmets donated by Spokes, Inc. through the Fairfax County Park Foundation.

Discovery Trail Maps will be available at any staffed Fairfax County park, RECenter, nature center, historic site and golf course (while supply lasts) and any Fairfax County Public Library (while supply lasts).

Instructions for participating in the activity are included on the map. The promotion runs through Monday, Sept. 5, 2016.

Parents/guardians of the bike winners will be notified by e-mail and/or phone. Bike winners will be publicly announced in September. For more information contact the Public Information Office at 703-324-8662.
