This concludes my 80305 project, which I started last April and occasionally worked on since then, generally when trails were muddy.
The GPS track should explain the project.
On the first day my printer declined to print a map, at which point the project became a significant map memory exercise. I spent a lot of time before many runs, designing an efficient route, and memorizing every turn; there were rather a lot of them.
I saw some things along the way, including a hamster wheel for dogs, a bench made from a ski lift chair, and a dragon.
