I watch more "old" stuff now, than I did back when it was new. I can't stand most of the newer shows on TV, compared to the modern dreck the Stooges and the Honeymooners are Shakespeare. Thanks to Amazon Prime and other streaming services, and the magic of DVD/Blu Ray, I can watch tons of awesome shows.
One of my bigger surprises was watching Route 66. I ignored it back in the day, always assumed it was just a situation comedy about a couple of Beach Boy types. Was amazed when I finally started watching it, to learn that every episode was a drama shot on location somewhere in the USA (rarely if ever on Route 66). They went all over the place, and the boys were shown working at actual jobs. It is fascinating to look at how different the towns were back in the early Interstate days before Generica took over and made everyplace the same.
