More than 14,500 kilometers of open road, circling an entire continent. A journey so long that the seasons change around you—tropical storms in the north, alpine winds in the south, red-desert heat in the west.

Want to take a year-long road trip in which the high temperature is close to 70 degrees the whole time? A dude from Alaska named Brian Brettchneider has mapped the course. It starts in San Diego Jan. 1, is near Minneapolis in June, Fairbanks in July and takes you into Florida in December. Here’s the year-long road trip that would follow the best odds of ideal weather. Covering 13,909 miles, the route navigates enormous stretches of North America, shifting north and south with the changing seasons. The goal? Get as close to 70-degree conditions as possible.
