Behold an extraordinary cartographic representation above, illustrating a staggering 9,125-mile (14,685 km) odyssey across the vast expanse of the United States! This epic journey has been meticulously designed to ensure a constant, comfortable 70°F (21°C) normal daytime high temperature for those brave enough to embark upon it.

This exceptional endeavor relies on data from the esteemed National Centers for Environmental Information (NCEI)—previously known as the National Climatic Data Center (NCDC)—specifically, the 1981-2010 climate regular database they've so expertly compiled.

Imagine setting forth from the sun-kissed town of Brownsville, Texas, close to the US-Mexican border. Picture traversing the length and breadth of this great nation only to find yourself, upon the journey's end, in the glorious coastal city of San Diego, also situated tantalizingly close to the US-Mexico border.

Curious, why three months spent exploring the rugged landscapes of Colorado? The answer lies in the majestic Rocky Mountains—a rare sanctuary within the United States that provides a haven from the searing heat that typically exceeds 70°F during the sweltering summer months.
