I was hoping the polygons on this page were accurate: https://satellitemap.space/

I do see a reference from a thread a long time ago that suggests a cell is perhaps 15 miles diagonally.

I'm hoping the geo locking is removed at some point soon so I can take it with me when I go RVing in the sticks.

But back to my original comment, I meant I can probably get Starlink at any rural location, as a fixed site, so I can work from anywhere.

The system simply doesn't have the capacity to serve lots of people in a small area. It only works if they geo-fence people into sparse, widely-spaced cells. Starlink is very upfront about this. There is very limited bandwidth per square kilometer of earth-surface. It isn't meant for cities.
