30,000 will fill Fenway Park, which is a very small park as baseball parks go. I think they have since expanded, because Fenway is always full. So...30,000 is a big crowd, but not unimaginably big.
Looking at the crowd, I believe it is possible.
12 More Years!
If you count the overflow crowd - it is quite possible!
The Indy 500 Speedway holds about 300.000. Wouldn’t that be fun!!!
I’d go! (lived in Indy for about 10 years and know a bunch of Repubs there.)
