rika and Nadia are planning their epic summer road trip across North America from Jackson, Wyoming. The plan is to pilot their camper van to as many national parks as possible in a three-month period. But first they need to plan their route in order to budget the amount of money they will need for fuel. They open their map app, and add the first few majestic destinations they have in mind: Grand Teton, Yellowstone, and Glacier National Parks.
