Sunny day outside, and I'm playing with maps inside. My next door neighbour is chopping a tree down so I keep looking out of the window to see how he is doing. Not a very big tree, but in the wrong place. Now it's getting a bit technical, he's just tied a rope to it. I think a branch needs to fall towards the road so it doesn't bring down the telephone wire. There are three men on the job and none of them are wearing any protective equipment whatsoever. No helmets, no goggles, and just an ordinary ladder to shimmy up the tree. Now the rope has been taken off and re positioned higher up. There's a lot of conversation going on, do it this way, no do it that way. There goes a big branch, must stop being nosey and get on with this.
Maps, now which route should I take? First look on an atlas.
Then stick some pins in a bigger map on a board. Guess the route at this stage.
Aha, another use for pegs. Borrow some Ordnance Survey maps from the library, fold and peg them together and lay them on the floor.
Now look at the maps in more detail, searching for the best options, not too far from civilization for a better chance of finding a bed for the night. Note down on a piece of paper several possible routes, then check the footpaths between towns and villages.
