HOULTON, Maine — The Anah Temple Shriners will descend on the greater Houlton area for the group’s annual Summer Ceremonial in June, but the 200 people attending will stay in some unexpected places. The June 16-18 event marks the first time in a decade that the Summer Ceremonial will be held in the Houlton region and just the sixth time since 1967 that it will be held in Aroostook County.
