by Erica
(Winston-salem, NC)

1) Any history about Niagara Falls?
2) How many gallons fall per second?
3) What kinds of animals usually pass through there?
4)Any interesting fun facts?
5) How much space does Niagara Falls take from NY to Canadian Border?
6) Any additional things I need to know?

Thanks.
