Slightly OT...
My ambition is to wallpaper the downstairs loo with the local OS maps, then draw in all our cycle routes.
We have a large sale UK map in the dining room that shows all our tours and the Coastal Route we did / are still doing,
OpisometerI have about 6 or 7 OS maps plus Memory Map on the laptop. If I'm going somewhere new, I'll download the route to a GPS and print off the route from Memory Map as a backup.
Before I got Memory Map, I had one of those little wheel things (looks like a mini pizza cutter) that you moved along the map to work out the distance accurately.
