Amazing workmanship! There are so many things he had to develop from scratch! Hats off!
But at the moment I prefer my own setup as it's a lot cozier. But if you'd work with other materials and put some decoration in, his track could be quite cozy as well. And there are quite a lot of things you don't want to fail in the bush. But then again if you have built the whole thing, there are few situations you cannot solve.
