Feel like going to LONDON from DALLAS but take a detour in BERLIN by the word change game.
All are six letter towns. You can change up to TWO letters at a time and make a new word. The new 6 letter word MUST BE a town, village, city, commune in Europe.
Cannot rearrange letters before or after the change.
Can you go from DALLAS to BERLIN to LONDON in 7 steps or less?
