Souvenir time. Hot places, Scottish places, Canadian places. All give you ample opportunity to bring something home. When you are looking for something to remind you of your Niagara Falls trip, what is better than this.
A beer stein in the shape of a barrel with something sorta maybe looking like Niagara Falls if you squint (or have used your beer stein a few times) on it. I know when I think of Niagara Falls, this is what I think of.
