Published: 7/12/2021 4:43:42 PM Drivers cresting the hill on Cathedral Road in Rindge are greeted with a sea of small American flags at the entrance to Cathedral of the Pines. Each of the 660 flags represents one of the 660 veterans on average who die by suicide each month. The display, called “Flags for Forgotten Heroes,” was installed on Saturday, and will stay in place through Veterans’ Day. Event organizer Bill Rohr, himself a Vietnam veteran, opened up to the gathered crowd Saturday about his own struggle with mental health, recalling a time when he had thoughts of self-harm, but was able to call a help line and take himself to the hospital.
