Top cities (1 tracked)
Top drawbacks

- ✕Summer wildfire smoke affects air quality regularly — July through September can have multiple weeks of AQI 150-200+.
- ✕Idaho is deeply conservative politically, with some policy shifts (abortion, LGBTQ+, religion in schools) recently tightening. Boise specifically leans moderate; the rest of the state is more conservative.
Massachusetts (MA)

Top cities (1 tracked)
Top drawbacks
- ✕Housing cost is the big one. Greater Boston is among the most expensive US metros, and it's not just the city — close suburbs are similarly expensive, with the 'cheap' far suburbs still above US median.
- ✕Winters are cold and long. Boston averages 48 inches of snow per year, and coastal storms (nor'easters) can drop 18-24 inches in a single event. Winters last from mid-November through early April.
- ✕Drivers are notoriously aggressive in Boston — narrow roads, confusing intersections, and a local driving culture that surprises newcomers. Rental car insurance rates reflect it.
