After this strange stop we moved on to the city center where he left me. I was on my own now and started to explore the little streets of the old center. It was packed with international visitors.
On Friday we are flying to Switzerland and then on Monday we will continue to Boston, Maine, Vermont and New Hampshire. I am very excited. Maybe this is going to be a great experience again.
After a short guided tour we came back to pick up our luggage and left to the airport. When the airplane took off it was already dark outside. We were surprised about the airline's good condition and service.
