In the spirit of Halloween, I just had to share the following account of an actual sighting.
We sometimes camp along the Arkansas River near Howard, Colorado, which is where the cemetery is located that initially sparked our curiosity. We'd heard about the "dancing lights" at a local restaurant, so one night a bunch of us piled in the car after dark hoping to see them for ourselves. And much to my shock, WE DID! It was such a show of lights that when I got back to Denver, I went to the public library to do some research as there had to be a logical explanation for what we had observed!

What I found was an article from National Geographic (August 1969, Volume 136, No. 2). They had actually conducted a study at another cemetery in Silver Cliff not far from Howard. Of course our next visit to the area meant another cemetery trip, but this time to the one in Silver Cliff so we could compare "sightings". The light show was again spectacular!
Think I've lost it? Let me support my story by linking you to an article written by Rocky Mountain News referencing Silver Cliff and it's Ghostly Spirits.
And if you're ever near Silver Cliff OR Howard, Colorado, plan a visit to the cemetery after 9:00! OH... and I should mention there are plots still available at both cemeteries. I hear they are both so popular people are just dying to get in!! ha-ha-ha-ha!!!
Interesting story and perfect timing. Such a busy day and week I am enjoying reading something other than real estate. By the way, create pumpkin.
