Manufacturers is a great course; actually it was my favorite find of all the courses I played with Gil Hanse that summer we built Stonewall. The people mover was out of service at that point, but I was a lot younger, too, so the walk back up to the clubhouse was no problem.
I'm actually working on a course where I think we might need a people mover to get people DOWN a hill. It's very steep and it goes on for a long way.
If I can find the right mechanical engineer, I think there ought to be a way to get the people mover to return to the top of the hill just from the energy absorbed in bringing people down.
