New Cardinals Stadium

I don't remember if we had talked about this, but I found a story on the new Arizona Cardinals stadium. The removable turf design sounds pretty cool. The field will be natural grass that sits outside and on game days they just roll it into the stadium to play. The story says its been used in Europe and Asia, but this is the first time I ever heard of it.
