Overlooking the Moran Prairie is the Immaculate Heart Retreat Center, an enchanting facility that hosts a number of programs and retreats throughout the year. From March 1-3, Immaculate Heart will be hosting a retreat for men and women about Mass based on (and named after) the Rev. Jeremy Driscoll’s book “What Happens at Mass.” The retreat will detail the true nature and importance of Mass, both traditionally and theologically.
