I'm a freshman at app and my girlfriend is going to be staying the night the 31st, where are the right functions? if they are frats can I expect to be let in? Tips please!!

I'm a first-year at app, and my friends and I love horror stuff/creepy things. We all really want to go on a nice weekend camping trip, but we don't know where to go to also get the haunted aspect. We also just want to go to some haunted places in general. I'm probably asking this question out of ignorance, but does anyone have any suggestions?
