Theoretically, a tumbleweed (Russian thistle) could keep rolling across the Plateau unimpeded. But there is a reality in fences and other obstructions that prevents an eternal journey. In this case the trip was cut short by a barbed wire fence. We all seem to come up against barriers sooner or later. I think it is interesting that tumbleweeds live their live as green plants but only become nomads in their old age. As humans, we talk about settling down, but I think that really can't happen.
