Searching a penpal to improve my englich

Hello everybody. My name is Björn and i live in Germany. I am 31 years old
My dream is to do a round trip through the USA but my english isn´t good enough for this. So i am looking for a penpal to learn more english words, grammar and phrases.
This penpal friendship should be more than only a teacher - disciple relationship. maybe it come up with a real friendship.
And now i hope to her from you very soon.
