As well as personal use, I've been using Route Cards (& planning) with Scouts ever since I have been involved (~20 yrs) so I'm doing my best to keep this practice alive with the latest local generations of emerging walkers!
Every year I organise a Scout hiking competition for our District. They don't know where they are going until they arrive at the starting point (and that is only provided a couple of days in advance to allow transportation planning). Then they are given a completed route card and are then expected to work out the route using the card and their map (they know which map to bring) and then walk it unaccompanied (but with lots of observation from afar!). It's then that we see how well their Leaders have trained them! No (GPS/GNSS/Satnav) allowed...partly as not all would have access to it so those that do would have an unfair advantage, but also to 'force' them to learn traditional map/compass skills.
We usually end up with little groups of young 'uns wandering aimlessly around the countryside and we sometimes have to despatch leaders to go and 'recover' them but we haven't lost any yet (in a permanent sense!) and they, at least, seem to enjoy it and, hopefully, learn something too!
