As plans to restore Healan’s Mill gain momentum and the number of advocates continue to grow, the future is looking brighter for the crumbling landmark off Whitehall Road near Lula. The 170-year-old gristmill is the county’s last surviving structure of its kind, according to Abit Massey, organizer of an advisory committee created specifically to restore Healan’s (or Head’s) Mill. Massey said enthusiasm is indeed growing and the committee has expanded from a couple dozen original members to nearly 60 as of Friday.
