If you prefer the cold, dark excitement of October's Halloween to the sweltering heat of a SoCal July, then the Midsummer Scream Fest could be your air-conditioned dream -- or nightmare -- come true. This horror extravaganza delivers plenty of thrills and chills via walk-through haunted attractions, theatrical performances, makeup demos and workshops, a humongous themed marketplace and even a costume dance party headlined by members of Oingo Boingo. That's not to mention the exclusive previews of coming attractions from Queen Mary's Dark Harbor, Universal Studios Hollywood's Halloween Horror Nights, Walt Disney Imagineering, Winchester Mystery House, Knott's Scary Farm, Six Flags Magic Mountain's Fright Fest and Blumhouse. So whether you're a fan of the macabre, a Halloween industry professional -- or fall somewhere in between -- you're sure to have a truly frightening amount of fun.
