Without GPS

Satnav saved us from mistakes and, along the way, from the feeling of knowing where you are.

Pick a place you have been to but whose route you remember badly: a district, a park, a friend's house. Look at the map once before leaving and memorise the direction and two or three landmarks — a river, a main street, a tower, a park. Put the phone in your pocket and go from memory, asking people for directions if you need to. Allow yourself to get it wrong and double back: that is part of the task, not a failure. Take the phone out only if it gets dark or you genuinely do not know where you are.

What did you lean on with no map — memory, other people, or guesswork?
