I didn’t quite know what to expect when I was asked to serve as “tour guide” for descendants of Dennis Sheedy during a recent visit to Denver. By no means a historian, I was a bit nervous. Heck…I’d only been working at Unbridled for a month, with just a brief overview of the “story behind the man and his mansion.”Beyond that, I knew close to nothing about the 125-year-old historic landmark the Unbridled community now stewards.
