I normally put my general info in profiles. Most often for city I use the nearest large city, because I live in a small town that most people have never heard of. For all intents and purposes, it's no longer really a town and the name only exists on signs placed on old abandoned tracks, and the deed to my house
Must run in the family because my brother's garage in Virginia was the original post office/general store for a town that sometime in the 20s was moved up the road 5 miles. (the town was moved, not the post office) but everyone knows where that place is, just don't try to get directions to the 'new' town.
