A Magic Picture Box

Have started to grapple with the joys of Satmap. For those who share my limited grasp of the world of electrickery, this is a small box containing all the Ordnance Survey maps of Britain, folded extremely tightly of course. Wherever you go, a little blob of blue in a blue circle follows you, like a clever but unimaginative collie . What is even cleverer is that the box of maps remembers exactly where you went (like your missus) and then you can save the route, or use it in reverse, or any manner of cunning tricks. The big idea is that I can follow a route around all the back roads near the coast, but can avoid the myriad of time consuming dead ends and the consequent torrent of vile language that will inevitably ensue. Although the technology is unimpeachably modern and of the moment, what slightly takes the shine off the deal are the failings of The Eyeball, Mark One. Either ride along peering through my famously reviled Ann Robinson specials, or run a screen scale so huge that you can only see about 100 yards of map in any direction, thus being unable to see whether the turning on the left past Mrs Miggins' cottage is a dead end or not.
