Binnendieze

An excellent, and mainly underground, boat tour of what was until very recently the sewer system of the town.  From Wikipedia on Den Bosch: 


"Hidden below the old city is a canal network called the Binnendieze that once spanned 22 km (14 mi). It started out as a regular river, the Dommel, running through the city in medieval times but due to lack of space in the city, people started building their houses and roads over the river. In later times it functioned as a sewer and fell into disrepair. In recent decades, the remaining sixth of the old waterway system has been renovated..."

I'm certain Ed Norton and his lodge mates of The Loyal Order of Racoons would have saluted the tour with a shake of the tail!

Loyal Order of Racoons say "Great Tour!"
