It's probably clear I'm no genius here, but how can I tell when a city will fire on me before I get shot at? For example, the Knights took a bunch of bases last night and finally I decided to land somewhere safe which was deeeeeep into Knight terriroty and prior to landing at field overflew some city not marked on the map and got the one ping ack death. Is there an easy way to tell or do I now have to start flying around all these things?
