In reply to Nordie_matt:
Interesting to hear that whsmith seems to be the place to go for maps these days. Guess its quite logical.
Also interesting that people are just printing their own maps off. I guess the only issue is if you've got lost and gone off the edge of your a4 section, or whatever you've printed.
Obviously nothing stopping you do that on an OS, but it will be less likely as they're bigger.
Though do always find the route you want is close to one edge of the map annoyingly, that'll be where print your own come into their own.
