I learned yesterday that a very popular gay resort in Michigan, The Dunes, is holding holding its "underwear weekend" (Aug 7-9) followed by a Swimsuit Tea Dance on Sunday afternoon. I was able to get a room for Sunday night, but will be staying off site Friday and Saturday. The pool alone is worth a trip to The Dunes, so I can't imagine what an underwear weekend will be like!
