Borders can be defined in many ways.
On your standard map they are hard ridges that define a country, state, city, town or village.
Round my neck of the woods, they’re defined by Hillsides, Mountains, lakes and Forests.
Depending on where you live, you can cross a number of borders within an hour
Even more if you travel by train or by plane
Reality is – you wont know if you meet a border till you get to a crossing.
