As part of its alliance with the National Guard, Six Flags, the world's leading regional theme park company, is offering active members of the Guard free general admission one-day tickets to any US-based Six Flags theme park during the month of September. The offer is valid for the Soldier, and up to three dependants. If a Soldier is on active duty (overseas or deployed), the spouse can use his/her dependant card to take advantage of the offer.
