I had to break apart a list of towns and did it by # of letters. Then when you gave the first letter of each, I dropped them in and made sure it was a good order, did the first few by process of elimination. About 5 minutes in I was able to start guessing fills based off of "does it have a third letter that's A?" It's fun cause the H city (the last down one,) has two options that both work for it
