Back in late March of 2016, Mike G. and myself made an expedition into the woods of Central Worcester County for the purpose of locating a possible smallpox den. The initial information was courtesy of a local man's map of historic sites in the area. It was also mentioned the initials BAB, with the date 1819, might be present at this site.
Mike and I were unsuccessful on that particular day in locating the 'cave'. But it was not for long! He returned in the Fall and located the site not far from where our wanderings had taken us. And yes - the initials BAB, along with the date 1819, were visible.
