It is not inherently true that a call that crosses state
boundaries and LATA boundaries is long distance. (And a call of 10
miles even then was usually carried on a carrier system, as copper for
thousands of trunks was prohibitively expensive.)

Many local exchanges and calling areas cross state lines and
LATA boundaries. A notable example is the Kansas City, Mo.-Kan.
metropolitan exchange.

Other well known ones include Texarkana, Ark.-Tex. (that's the post
office name, too ... the post office sits astride the state line);
Fort Smith, Ark. (a lot of it is in Oklahoma); Texhoma,
Okla.-Tex. (the elementary school is in one state, the high school in
the other); and one with which Pat is no doubt well familiar,
Coffeyville, Kan.-South Coffeyville, Okla.
