To think 250,000 people can all gather in one place is pretty incredible.  Especially considering the population back then was only a fraction of what it is today and how difficult travel was at the time.  I dont know if I would be able to sit through some of the violence that took place there but it would be something to see.  Especially with 250K people screaming and yelling the whole time.

I wonder if they ever reached maximum capacity at the circus maximus? Which event would you want to see most if you could go back in time?
