We are going on a trip to the Netherlands.
First we will visit Amsterdam, and we will go to Hengelo. Amsterdam is a bigger city Hengelo. But I like Hengelo more Amsterdam.
In Amsterdam we will visit the zoo first, and we will visit a museum. This museum is mutch older the museum in my hometown. But the zoo in Amsterdam is smaller the Zoo in London.
This trip is going to be more fun any other trip I ever made!
