San Antonio's 13th Floor Haunted House is turning off the lights for 'Blackout' event

San Antonio’s 13th Floor Haunted House is getting even scarier next month for its "Blackout" event, according to a press release. Between 7 p.m. and 9 p.m. on Friday, Nov. 11, the haunted house will turn out all of its lights, and those brave enough to enter will have to navigate the 13th Floor — ranked among the scariest haunted houses in the nation by the Travel Chanel — with only a glow stick to light the way. “Blackout is our favorite night at 13th Floor San Antonio,” general manager Blaine Skreenock said in a statement.
