Well I looked around and that picture links to this post: http://www.belltreeforums.com/showthread.php?199457-What-kind-of-paths-do-you-use-for-your-town the picture the user "TeeTee" posted apparently links to the one you just have just shown. Seems the user is still active so you could ask them. They also said the path as featured on Bidoof once but I can't be bothered to look that long lol
