The Feast of Ste. Claire is held every Memorial Day weekend in Port Huron, Michigan in Pine Grove Park. The events take place on Saturday and Sunday only. Re-enactors, encampments, crafts, food and music are featured. I've only been there once, and it featured a mock French-Indian War battle. It's worth taking a look at.
