You draw the line, not a radius somebody else chose
Most apps guess. They take your location, pick a radius, and hand you a city forty minutes away while missing the village ten minutes down the road.

Pick towns by name
Search any town in the United States and add it. The list covers around a hundred thousand real settlements, so the one you mean is in there even if it is three hundred people and a gas station.
Or trace it with your finger
Draw a shape on the map: your side of town, the stretch between two towns, the few miles around where you work. Take a whole county in one go.
Change it whenever you like
Borrow an area for a few days while you are travelling, then drop it.
Every event is a coloured dot by what kind of thing it is
Festival, performance, competition, class, conference, gathering - so you can spot what you like without tapping. Turn off the kinds you do not want and they disappear.
It works anywhere - and here is the honest part
You can set this up in any town in the country today. Whether there is much on depends on who is posting there. Some areas are busy; some are just getting started. If yours is quiet, that is an opening rather than a dead end.
