In the second half of this two-part episode, Madi and Rosario are still trying to get a message to Ruff's friend in Hawaii - even though Ruff has only sent them as far as Colorado. They learn about reading topographical maps and compasses, and get on a dogsled to cross the Continental Divide and throw Ruff's message into a westward flowing river, trusting that it will eventually find its way to Hawaii. Willie and Nina continue on their race following Paul Revere's famous ride through the streets of Boston. They must solve puzzles and learn about the Revolutionary War to complete the challenge.
