First, I'd like to apologize if my consideration doesn't apply to your software. I haven't used your app, I'm just saying that borders are sometimes a hassle, and sometimes necessary, when it comes to software that involves a geographical area. Depending on context, sometimes the distance from me (no matter where borders are) is the only important factor. In other instances, jurisdiction of silly rules are the main factor. In the Oklahoma example I provided, let's pretend I'm using an app to buy a car. I'm willing to drive 75 miles to buy one, but only if it's in my state. Or if I'm job hunting, maybe I'm willing to commute 50 miles, but not if I have to go to Colorado. This type of logic is missing from nearly every common software that makes use of geography.
