You may be thinking I have forgotten all about postcards, amid the current flurry over archival news photos. Not a bit of it. Once one of the elder step-sisters took all of us kids--I was about 12--to a somewhat squalid roller rink in East San Diego. (Not like the nice Belle Epoque one here.) Indeed, that's where I learned to do the hokey-pokey. And that's what it's all about.
