I think the last time for me was 1990 or so. It had been a few years after I was out of the fire service and was doing volunteer comms for the town parade. I was in the staging area coordinating the various units the last of which was a fire engine from a neighboring town. I hopped on the tailboard as it departed the staging area and road down the parade route.
There was nothing like holding on the back of a 1953 Mac pumper that was bouncing over the county roads at 80 mph holding on to the bar for dear life.
If that video was 1961 that airplane had to be at most 2 years old. The swept tail 310 was introduced in 1960 if my memory is correct. Wonder if it was fixed and is still flying.
