San Jose

San Jose

San Jose is Silicon Valley's anchor city, much bigger than San Francisco by population, and culturally underrated because everyone drives through it on the way somewhere else. The Vietnamese food scene (especially in Little Saigon) is one of the best in the country. The weather is impossibly mild, the Santa Cruz Mountains rise to the west, and the tech money funds a genuinely excellent restaurant scene.

Huntsville

Huntsville is Rocket City, with NASA's Marshall Space Flight Center, the Saturn V rocket on display at the Space and Rocket Center, and a tech and engineering economy that punches way above the city's size. Cummings Research Park is the second-largest research park in the U.S. The Tennessee River and Monte Sano State Park give it a quiet outdoor side. Affordable and surprisingly smart.
