Ledertreffen Hamburg

The world's oldest operating leather party, Ledertreffen Hamburg is a weekend of parties and activities, drawing fetish fans from around Europe and beyond. The calendar also includes a little sightseeing and a bike run, but the highlight of the weekend is the Saturday night party aboard the MS Stubnitz, a mid-20th century freeze-and-transport vessel. Cargo holds, it turns out, have great acoustics.
