Michal bad news waiting for you in Gliwice, they have banished trams from the city centre..
My father used to lecture there and I remember taking walks in a very small forest / park near by.
That park is still there, really beautiful in the Autumn, and they have just recently mowed down trees that were growing around and inside the stadium nearby..
