Imagine ZORBing in Detroit's Rouge Park

I discovered this thing on-line called ZORBing, which is basically rolling downhill in a large inflatable globe.

It looks like a lot of fun and I keep thinking: how awesome would it be to do something like this down Derby Hill in Rouge Park?

There are currently only a handful of locations in the world where one can go ZORBing, with the closest one to us being in the Smoky Mountains of Tennessee. However, I think this would be a really cool thing to bring to Michigan and I can't think of better place for it than Rouge Park.
