All I could think about when at Niagara Falls (beside how beautiful it was) was Lois Lane in Superman II when she threw herself off the Falls. "Bye bye baby!" Of course, on the Canadian side, you'd probably not land in the water if you did that. You'd break all your bones on the rocky cliff.
Near the end of the Falls, there are a lot of seagulls and other birds. It's amazing that they are not afraid of people! So many people were getting right in their faces to take photos. Myself include!
