For a mere $25, you can have the scare of your life by heading to Ulster Park, NY. Headless Horseman Haunted Hayrides have been the scariest Halloween activities around for some time, with good reason. The company employs over 100 actors to make the nightime hayride in a rural part of Ulster County absolutely terrifying. I almost fell off the truck last year, one of the ghosts scared me so bad.
There are other things such as a haunted house, once you have completed the hayride. Reservations are a must, as this is a popular destination! I don't recommend going on a rainy night, as the mud can be quite slippery.
Give this place a try. As scared as I was, I was laughing the whole time because I had so much fun.
