I've moved to a new neighborhood and there's a forest nearby. Today, to get a better idea of all the trails, the dog and I wandered every trail we could find. I also has Sports Tracker on to see what a trace of the ramble might reveal.
The resolution of the GPS kept some paths that I walked over more than once from being overlaid, showing two parallel paths.
But, for me, it gives me an idea of all the paths I can walk there.
