Thanks for sharing this interesting map, @AmieComeau! Is there a question you had wanted to ask our Community of members? If not and you're instead trying to start a general interest conversation around the map, I'd like to help get this post moved from our ArcGIS Online Developers Questions Board to our more general GIS Life Discussions Board. As one of our Community Managers, I can move this post for you but want to make sure I understand what you're looking for first.
