A man was hurt this weekend in a golf cart crash at a nudist resort in Anne Arundel County, Maryland.

The man crashed into a tree Saturday afternoon at the Maryland Health Society, The Capital Gazette reported. The group is the oldest nonprofit, clothing-optional health resort and campground in the country, its website says.

The man suffered serious but non-life-threatening injuries after crashing into a tree, causing the golf cart to overturn, the Anne Arundel County fire department said. He called 911 from a building at the nudist resort, where he was either staying or visiting.

He was not wearing a helmet at the time of the crash.
