Final answer:
To travel from the Great Lakes region to the Rocky Mountains, one should head westward.
Step-by-step explanation:
If you live in the Great Lakes region and want to visit the Rocky Mountains, you should travel westward. The Great Lakes are located in the northeastern part of the United States and southeastern part of Canada, while the Rocky Mountains stretch from the northernmost part of British Columbia, in Canada, to New Mexico, in the southwestern United States. Therefore, to go from the Great Lakes to the Rocky Mountains, you must travel in a generally westward direction.
