I looked a little more into Biden's beach house In Rehoboth's gay beach town. It's interesting that there used to be a gay dance club there where closeted politicians would meet, it was called "The Renegade".
While The Pink Pony was destroyed by the great 1962 storm, several miles south along the shore, the Nomad Village had opened. Closed in the 90s, the hotel and bar complex catered mainly to men and women staying at the Nomad hotel. But word spread that the Nomad backroom was a great meeting spot for closeted folks from D.C.
Through the 1970s, Rehoboth's reputation as a traditional family resort continued while more gay visitors arrived. Two gay dance clubs, The Boathouse and The Renegade, opened to celebrate the disco era, and 300-400 gay men could be found on the south end of the beach on holiday weekends.
