Freiburg's trademark is its system of Baechle, tiny streams running down each street. As you can see they weren't filled with water today. These go back to the middle ages (serving as fire protection, cattle refreshment, and a constantly flushing disposal system). Local lore says that if you fall into a Baechle, you are destined to marry a Freiburger. Hmm, since Isabelle jumped into it...I wonder what her future holds!
