The intention was to use the first letter from the name of the first city, second letter from the name of the second city, third letter from the name of the third city, etc. Case mattered, which is what St. Louis and Baton Rouge were included in the middle and end.

Hints:

• "The order is very important," which should sound odd, because the clues to the hidden digits are usually already in order.
• "Enjoy each location at length," as in "the entire word," or "beyond the first digit."
• "19,770,609,664 permutations." This one was a bit tougher, but was a response to claims that there were XYZ number of possible URLs. 52^6 = 19,770,609,664, so there are both capital and lowercase digits, but no numbers. I'm told this was too hard and I'll remember that for next time.

I had planned to give more hints, but people were solving it quickly enough, and I had planned for around two dozen or so entries.

Thanks for all those who participated. There will be more puzzles in the future. See you!
