To get the clue to your next destination, though, you'll have to solve one of your toughest riddles yet: a cipher. Take a look at the letters below:
JMV BIV LZC ABG
To solve this cipher, each of you will need to take a turn, starting with the oldest and working down in order to the youngest. Your instructions: rotate all of the letters of the cipher backwards through the alphabet based on the month of your birthday. For instance, if someone was born in March, they would rotate every letter back three, a May birthday would rotate backwards five letters, and so on. Once you've done your part, pass the cipher along to the next oldest person. Once all four of you have taken a spin at rotating the letters, they will spell out the clue to your next destination.
Good luck! We love you!
