A La Expo 67

Not really, but I’d been thinking of that amazing housing project in Montreal, built at the time of the 1967 Expo there. I saw it from the window of a Greyhound Bus in 1971, then thought of it again after my brother’s recent visit to Montreal. 
This is a group of condos, near us, built overlooking the Willamette River in the 80s. The units are perched on long stilts while the Expo 67 ones are concrete units balanced and supported by one another.
