Are there any horror fans or adults that will celebrate Halloween? Philadelphia has a lot of events coming up. There's always Eastern State Penitentiary for their haunted house. I haven't been during Halloween. I went during the summer once and can confirm it is haunted. If you're daring, a night tour at The Bates Motel may interest you. Fall festivities at local orchards are also a good option. There's a lot going on in the coming month.
