Patriots Point is not participating in Museum Day today.

The naval and maritime museum's marketing staff decided about eight weeks ago not to participate because it saw no financial gain from the ticket giveaway, but the Smithsonian magazine website continued to list Patriots Point as a participant until last week, Executive Director Mac Burdette said Friday. "It was a ticket giveaway, and we aren't in the business of giving tickets away," he said.

If anyone downloaded coupons before Smithsonian removed Patriots Point from the list, the Mount Pleasant tourist attraction will honor them, Burdette said.

Other participating sites in Charleston include the American Military Museum, Drayton Hall and Halsey Institute of Contemporary Art at the College of Charleston School of the Arts, according to the Smithsonian website.
