Six Flags New England is offering free admission to the park to those who carry one of four select names in honor of the 80th anniversary of “Batman.”

On August 17, anyone with the name Bruce, Wayne, Martha or Alfred on their license or valid ID will get admission into the park.

Anyone who is 80 years or older will also get free admission into the park. Those who qualify for the free tickets can pick them up at the Group Sales Window at the Main Gate.

Guests are encouraged to come and show their love for everything “Batman” by hopping on one of the rides dedicated to the many characters of the series, such as “The Riddler,” “The Joker” or “Harley Quinn.”

Six Flags New England plans to throw a party to celebrate the big anniversary.
