HUDSON -- It's a landmark season for the Hudson Haunted House. The twisted building is celebrating its 40th anniversary, which makes it one of America's longest-running haunted attractions.

The annual Halloween attraction that dubs itself the "Monster of all haunted houses," has churned out fright for decades all with the goal of raising money for various charities.

As is tradition, the Hudson Haunted House uses all volunteers to staff the haunted attraction. Many of the blood-covered teens lurking around every corner are actually local high school kids working to earn community service hours.

While many of its classic scenes remain (butcher shop, cemetery and vortex tunnel), the Hudson Haunted House features a variety of new scenes for the 2012 season.

Children under 48 inches are $5, but if they're too freaked out by the full night-time show, Hudson offers a special kid-friendly experience on Sunday, Oct. 28 from 1-4 p.m. The special matinee event costs $3 for kids (adults are free with paid admission for children). The kids will be given the opportunity to trick-or-treat inside the haunted house with the lights on and the monsters' masks off.

The Hudson Haunted House is located at 2250 Barlow Road.
