Another interesting example is Hyder, Alaska, which is only accessible by road from BC, Canada. It relies on various services from Canada, including ambulance and fire services, the latter due to Hyder's fire hall being burnt down, with their fire engine inside, during an Independence Day fireworks display.

There are no border controls when entering Hyder from Canada, as the only way to access the rest of Alaska from Hyder is via seaplane, and those flights are treated as international in origin when they land. There is a inspection station when crossing into Canada, but it is closed overnight -- anyone wishing to enter Canada when its closed must report via videophone.
