Around the corner from our Amsterdam apartment, we saw a traffic jam where the Prinsengracht and Leidsegracht canals meet.
The blue tour boat entered the intersection, stopped, and turned using side thrusters while the blue boat under the bridge waited.
After the tour boat got turned around, it proceeded to the right. The blue boat under the bridge edged out, and a red boat approaches.
The red boat approaches the intersection and stops.
And the blue boat finally proceeds. The passengers are partying and enjoying a Saturday afternoon in Amsterdam.
