Tip for the cautious: obey bike rule at the Hörnle

Actually there is no reason why you should not park your bike next to your spot on the lawn of the Hörnle. Then you could always watch over your precious bike. Makes sense, right?
No, the persons running the beach area say, and point to the large bicycle parking area outside the Hörnle entrance. In cases of noncompliance they have come up with this punishment: a bath attendant will “ground” your bike with a chain joint, uttering not a single word. And only after hearing your profound apologies will he open it up again. It’s not worth the trouble!
