Here is a brief history, with some stunning black and white photos. I also enjoyed my pilgrimages to Tulsa and Kansas City (barbecue too). Buenos Aires has the best public sculptures. I’ll nominate the Taj Mahal for the most overrated site; it looks just like the postcard and I liked the saris of the visitors more than the site itself. Here is a picture of Magnitogorsk, which I hope to visit. Here is a broader index of Magnitogorsk pictures. Brasilia is another dream of mine, and yes I do find that image attractive.
