I have plotted all the active meshnet nodes than I know of on Google Maps so it will be easy to find the closest one in your area. As you will see we have a long ways to go to fill in the holes.
Each location contains a link to the local node map and from there you can find the closest node to your location.

Also if anyone knows of any new or existing projects I have not listed please leave me a link and I will add them to the Map!
