Was the little cemetery St. James-Sag? It's where the ground is said to breathe and phantom monks chase people off the grounds. I believe the cemetery is on a fairly steep hill.
Archer Woods Cemetery is near there, too. I don't know why that part of Archer Avenue is so creepy, but there are tons of stories associated with the area.
I've taken the Richard Crowe ghost tour a couple of times and that is fun, too. It leaves from the Goose Island Brewery and I believe the first place you go is the site of the St. Valentine's Day Massacre. It goes through Chinatown, over train tracks where Lincoln's funeral train is supposedly seen and ends up at Resurrection Cemetery. It's a great way to see the city.
It could have been Archer Woods Cemetery. I will have to check. We also stopped at St. James-Sag, which now that I recall, was pretty eerie as well.
Ah, yes, Richard Crowe. I've never had the opportunity to go on any of his tours. Back in the 70s, he used to do an annual overnight Halloween broadcast on "Chicago" Eddie Schwartz's show on WIND radio. He'd tell all the well-known Chicago area ghost stories, as well as some lesser-known ones, and take calls from listeners with their questions & stories. That's where I first remember hearing of Resurrection Mary and Bachelor's Grove. They'd also play spooky recordings that, in retrospect, were probably more corny than anything else, but at the time seemed oh, so deliciously scary. I was just in jr high & HS back then. One of my favorite growing-up memories is sitting in the dark with my younger brothers every Halloween night, listening to this broadcast, and scaring ourselves just silly.
