Need and want are different. I seldom need to consult a map, but I want to. I enjoy looking at maps. It is nice to verify the features that I identified while planning at home.

A type of orienteering competition is a "memory" meet. There is a map at every control with the next control marked. You spend enough time with the map to plan your route then leave the map at the control and go to the next control without any map. Memory courses are often used to train.
