I'm planning on buying a map to use as a backup to my GPS. Before you all start on me, I have no intention of using it for primary nav, and it will probably just spend ages in my flight bag - hey, I bet if I ever need to use it, I'll find that I've forgotten to refill the lead in my propelling pencil !
Anyway, I've looked on all the usual web sites, but there seems to be a really confusing variety of maps to choose from - can you clever chaps help please ? Ideally I'd like to get one delivered in a plain brown wrapping in case the chaps down the club get wind of it ....
