Which sports stadium (meaning any building designed to host sporting events) in the world, is the largest and who plays there? I'm thinking the largest as in the amount of people it can hold, but if you can come up with something different to go by, that's fine.
I am including any stadium that was made or designed to house any sort of sporting event. Motor racing is considered a sport so that is valid.
I think I read somewhere that the University of Michigan Wolverines have the largest capacity stadium in the USA. Is that true? And if so are there any larger than that?
