geography nerds?

I recently had a bit of an adventure in a snowstorm while driving
across the country. When I called AAA for help, I nearly got into an
argument with the dispatcher when he wanted to know what town I was
in, and I insisted that I wasn't in any town, but out in the country
with no nearby town or village.

Is anyone here enough of a geography nerd to settle this? Is every
part of the US within some city limits? I'm thinking the answer is no;
every part (except D.C.) is within a state, and within a county, but
there are substantial areas that are unincorporated, and thus not
within any municipality (city/town/village/whatever).
