Niagara Falls, I have been there twice, the first time was 15 minutes on the US side only, the second time we stayed on the Canadian side overnight. I remember two things on the hotel, the doorman mistook my wombat for a beaver (a stuffed wombat who was traveling with us that summer) and the hotel had "free wired internet access" but the free didn't include the cable. They wanted to charge $15 to "rent" a cable overnight. Silly.
Travel Penguin was rather taken by all of the wonderful water, fortunately he didn't dive in. I have fished him out of the Mediterranean, and a gator infested swamps in Florida, but I don't think I could get him out of this, he'd wash up in Niagara by the Lake, sipping Ice Wine no doubt.
