The Kingston Penitentiary just closed after having been in operation since 1835 and they're selling tickets to tour the place. There's been an online bidding war for them since they went on sale! Then there's Fort Henry, a historic structure where they started having an annual halloween event every year called "Fort Fright". My daughter went through about 3 years ago and loved it, they've been adding things and tweaking it ever since, I might have to go. I've been to the Fort several times for other events, and it is a very spooky place in its natural state so it should be good and freaky.
