Do you know what type of this car (bus)? It's a water and ground car. (amphibian car?) We went to a lake, and rode this car. It ran 7 minutes as a car, and after that needed 5 seconds to change into a ship before a lake. After a rallying call like 3,2,1, 0, it splashed.
This lake is an artificial lake used as a dam. Here in Kuriyama area there 5 dams. They are flood control dams. Well, well, I knew this fact this time.
After riding this car, we visited a dam, and studied about 5 dams a little.
The water of 5 dams are, of course, used in Utsunomiya, and used even in Tokyo.
The dam is in the mountain. And in the mountain did we have meat again? Not it's the time of SOBA.
Next day we went to hot spring, and at night watched fire works. During this season, firework displays are held here and there. We went to see one of them.
