Boo! 

The spookiest season of the year begins this Saturday with the opening of the Six Flags America Fright Fest in Upper Marlboro.

Starting at 6 p.m. on Saturday and Sunday nights through Oct. 28, the park turns dark, scary dark, according to park officials. This year’s Fright by Night, Beware of the Awakening, turns the park into a terrifying hunting ground for the undead.

There will be more than a dozen spooky attractions at this year’s event, including Blood Factory, Toxic Fallout, Road Rage Cage, Stage Fright and more.

Those looking for a more family friendly fall celebration won’t want to miss Thrills by Day, which will feature friendly ghosts and goblins, and kid attractions including the Monster Mash Bash, a Halloween Dance Party, the Hilltop Gardens Maze and more, according to a Six Flags statement.

If all of that doesn’t sound creepy enough, on Oct. 13 there will be a cockroach eating contest. The person who ingests the most roaches in the given time period will win a 2013 Six Flags season pass.

Fright Fest opens Saturday, Sept. 29, and runs every Saturday and Sunday until Oct. 28 with special Friday openings on Oct. 19 and 26 at 5 p.m. for Fright by Night only. Fright by Night is not recommend for children under the age of 13.
