Closest *Major* East Coast City to California?

If you measure from San Diego (SW corner) to Jacksonville, FL (SE corner), it’s ~2,100 miles (3,380 km) driving. From San Francisco to Boston, it’s ~3,100 miles (5,000 km).

The continental US spans ~2,800 miles (4,500 km) coast-to-coast. So the premise of the question reflects a common geographic mix-up—California is as far west as you can go in the lower 48.
