This is of the most fascinating human wonders I have ever seen. Hoover Dam, also known as Boulder Dam is a wonder of human engineering. It is located in the Black Canyon of the Colorado River, on the border between the US states of Arizona and Nevada.
I never forgot to visit its Souvenir Gift Shop to buy some memorabilias during our visit last May 2008. Its like a little Cyber Monday shopping I had in their souvenir shop. I bought a book about Hoover Dam, some postcards, magnets and keychain during our visit. Buying those stuffs already made my day. I wish to visit it again in the future.
