Just saw some hot gossip in the cycling community, totally eye-opening. I can only say this circle is a mess. A cycling group in a small city organized 10 men and 10 women to ride somewhere together and stay at a hotel in the middle of the night. They used a mind-blowing arrangement for the stay: it achieved mixed-gender lodging while maximizing the secrecy of who stayed with whom. The method was: 10 rooms were booked on a certain hotel floor. First, the 10 women went to that floor, each chose a room, closed the door, and were not allowed to come out. Then, the 10 men entered the floor, each chose a room, and closed the door. The next day, the 10 men left that floor first. Only after all of them had left could the 10 women come out and meet up outside. This achieved a male-female mixed stay, and only the two partners knew who each other was. As long as those two kept it a secret, no one else in the circle would ever know.
