In our road trip around Belgium and Netherlands, we have seen so many cities with canals. Almost every single city we visited have canals like blood streams. Although we have seen so many canals in those cities, first time ever we saw a traffic light in the canals when we visited Delft, Netherlands. Likely it is because I was negligent and did not notice (well, obviously I never expected to see traffic lights on canals). I heard that there are traffic lights on the canals in Venice, but I don’t remember if I ever saw one in Venice. Anyway, it was so “rare” to see working traffic lights on the canals and I found it very interesting.
