Hi Paul.
Yes! I do like your map, You did ask for suggestions so I hope you don't mind these comments.
1, Lighten the background to give more emphasis on the dates,times and comments.
2, Add some relevant commentary.
3, As you have probably seen from my previous pictures I have a liking for cameos depicting lifestyle or historical events.
Anyhow here is a quick idea of what I mean, I wont be worried if you don't care for these ideas - anyhow what other ideas are out there,
Denn
