Thanks for the feedback everyone:

@ Lukec - I see what you mean about the potential difficulty of writing on the map. However in my case, this is really only being used as a reference. I won't be printing it out. But that is a good consideration to keep in mind if at some point I ever do decide to print it out.

@ Larb & JT, thanks, I do like this style and will keep it in mind as I pay around with other ideas.

Cheers,
