I love Maps.
I use them all the time for my homework when I’m going to a new location.I have nearly the complete coastline of Ireland covered with the OSi Discovery Series 1:50 000 scale maps. However I also use these hand painted maps by Richard Chandler from Fir Tree Maps.

The map above is the one of The Iveragh & Dingle Peninsulas and along with the Beara Peninsula & South West Cork map I would use the most and stay in my camera bag. I love the 3D effect of the mountains which gives me a better understanding than the normal map relief features.
