Via Alan on Facebook came a link to this page of things one might remember from the Decade of Malaise and Disco.
The 110 film cartridge was timely, as Bobbi had just shown me a video clip of a model rocket being launched from a drone, with both the drone and the rocket equipped with video cameras:
They had model rockets with cameras back in the '70s, but they used 110 film, so you might need to wait a couple days to see a few blurry images of your neighborhood from a rocket's eye view.
Here at Roseholme Cottage, we still use ice cube trays, albeit slicker and trendier and more hip and modern than the ones we had in the '70s, just like we still have a progressive dunderhead for a president, albeit slicker and trendier and more hip and modern than the one we had in the '70s.
Differences from the '70s abound, too. The current president looks a lot more comfortable bowing to foreign royalty than the old one did kissing Soviet dictators, for example, and nobody's boycotting anybody's Olympics for invading Afghanistan this time around.
