When's the last time you set out to discover a mystery? A friend of mine called me a couple weeks ago to tell me about a small graveyard that she remembered from her days of working at Glacial Park in McHenry County, Illinois. According to her, The Thomas graveyard was nestled in the middle of this enormous state park and you had to hike to get to it. The prospect was too cool for words, so I put on my hiking boots and set out to find it, which we did.
