Here's a great little article from the Reminder about free lunchtime tours of downtown's Ancient Burying Grounds. Best of all, the tours are conducted by Hartford middle-schoolers, specially selected and trained.
In case the article goes away: "For more information about summer tours of the site, contact Andrea Ader
at 860-742-5234. For more information about the cemetery, visit www.theancientburyingground.org or contact the Ancient Burying Ground Association at 860-561-2585."
