I was looking for a better map to keep track of countries. One that has areas that aren't actually countries, like Scotland and Crimea, etc.. My friend showed me Mapbox and I thought it had possibilities. So, I started making two maps today and am liking it so far.
Here's one I started for this year's books: https://a.tiles.mapbox.com/v4/kmc3050...
I hope this helps someone!
