Tens of thousands of Vietnamese Catholics from all over the country are expected this weekend in Carthage, Missouri for the annual Marian Days. The celebration gets underway today but the major festivities, including a procession take place Saturday. Instead of staying in hotels, many visitors set up tents on the grounds of the Congregation of the Mother Co-Redemptrix campus. The center of the campus features the Immaculate Heart of Mary Shrine. Chairs and a kneeling rail are available for people who want to pray near the shrine.
