For three nights, the weather won't be the only thing to give you chills down your spine.

The Haunted Swamp begins it's three-night run at the Bitterroot Aquatic Center on Kurtz Lane in Hamilton. The twisty-turny corridors and fog-laden rooms will be inhabited by seasoned monsters, zombies and others to provide a surprise or two.

"Not recommended for children under 12" means that the creators of the Swamp have some nightmarish scenes ready to go. Money raised by the haunted house attraction will help buy equipment at the Hamilton swimming pool.

Admission is $7 per person and the Swamp is open this weekend only - Thursday 7 to 9 p.m. and Friday and Saturday evenings 7 to 11 p.m.
