Truckee, Calif., is a mountain town just northwest of Lake Tahoe. It is sort of an outdoorsy paradise. It has great skiing, mountain biking and hiking opportunities, as well as a river and lakes. It also has some great restaurants and a budding art scene. And if you’re a Bay Area resident in the market for a house, it has another thing going for it: It has a median home price that’s roughly half that of San Francisco, about three hours away.
