Please look at that list again. While it may seem like a never endless of cities, it's a somewhat limited list of states (with some exceptions, mostly focusing on the most populated states).
There are oodles of states that are not on the list. I don't see what's so "random" about living in Oregon, Indiana, Ohio, Nebraska, North Carolina, Hawaii, Alaska, Alabama, Louisiana, Tennessee, Maine, New Hampshire, Missouri, New Mexico, Arkansas, etc, etc.
Huge sections of the USA are not supported.
