My favourite means of transport.

My favourite means of transport is plane. This is the fastest and most safe means of transport. But unfortunately this is most expensive means of transport too.
I have been living in Germany and I and my family often travel in Poland. We travel by car because this is cheaper.
One in my live I fly plane. This was wonderful felling and I was very fast to make in Tunisia.
