These are strange times indeed (my generation's Vietnam ?). Hmm, time will tell.
Some things that I would like to see if I could go back in time would be: the Tiki Gardens in Florida; the New York World's Fairs in 1939 and 1964; the 1967 Expo in Montreal; and the World's Columbian Exhibition in Chicago in 1893.
I recently read a very interesting book by Rem Koolhaas, which discusses a concept known as Manhattanism. In it, a section is devoted to the fantastic Coney Island, the site of such wonders as Luna Park, Dreamland and the Steeple Chase. The descriptions of these places and the electrical lighting set-ups are incredible for the period.
What fun.
