I was thinking about how great it would be if my Lego Back to the Future time machine actually worked and one of the things high up on my list would be to visit DLR in the 50's then 60's then 70's.
then it dawned on me that I'd be pretty much money less. My 21st century cash would seem like counterfeits, my credit and debit cards would be useless. And just imagine me trying to enter the park with an AP card..."Son, I've never seen one of these!"
Was all this brought on by some TR I read? Possibly
