You may want to provide a clue (for the clueless) in the caption both here and on the main page that these maps are "best viewed at original size" - and even for those who don't notice that the little maginifying glass shows up - to click again.
Looks like a 10/10 map to me - but then I already had a clue.
That's a great idea Fred. I did put that info on a couple maps but for the most part have left it up to people to 'have a clue'. I'll go back and add that to all the maps.
