The baths in Vienna are quite interesting. The Austrian sauna culture is... also interesting. Everyone is naked but one person, usually a large man, fans everyone in the room with his towel while jumping... it's interesting to say the least. Interesting in the Chinese curse sense? The first time I went to the gym in Vienna, at this fitness center called "City Fitness" I was interested to see that the sauna/bath area was co-ed including a lounging area that is naturally lit by skylights. The first time I was relaxing there, two very hot Austrian girls sat down next to me completely naked. That was a good gym. Boing! In that situation, embarrassing things could arise. Or is it ruder not to respond?
