A map cannot show how welcome you will feel after you arrive.

Everything a map can tell you is about position: distance, elevation, where the roads meet. None of it touches the question people care about, which is whether they will be glad you came. Welcome is made by individuals in a moment and cannot be surveyed in advance, which is why research before a move or a visit only settles half the worry.

So gather what facts you can, then accept that the rest arrives only on arrival. And when someone new turns up in your own place, remember that you are the part of it no map could have promised them.
