The classic St. Mary’s Point Arena located on the St Croix River since 1968.
"The story of St. Mary's Point Arena began back in 1967 when the mere idea arose to long-time friend to hockey, and President of Hubbard Broadcasting - Stanley Hubbard, dreamt of having a covered building from the elements, where local kids could skate and play hockey. The idea was born, and primary funding and donation of land for the community arena came from Mr. Hubbard."
