impressed: When I went to see Niagara Falls for first time, I couldn't believe how big it was.  Mind blowing to see in person

Ever been to Niagara Falls? I just went and it blew my mind on the size of it!

I haven't been.  I would really love to go, and it's good to hear such a good review from someone.
human
Yeah, you definitely should go, very worth while.

What else is there to do there other than see the falls?
