Oh, yes. Absolutely. The cold, damp smell of a concrete parking garage returns me to a doctor's office I vusuted every week, thirty years ago. The smell of sunlight on barley, to an afternoon at the end of the industrial revolution. Burnt gunpowder to the backstage of a royal celebration during the ancien regime. A different smell for a different past, every one personal and unique. Simply the most effective time travel ever invented, as Proust discovered. Still unpatented, I believe. Some difficulty with returning to the present.
 

wow...what a visceral post that was. The smell of capgun smoke wafting through the air. I was right back there in an instant!

Thanks for the reminiscence!
 

Caps added excitement to childhood in a way that I don't think exists today ... but I think those snakes still exist, that one buys in black pellet form and lights on the concrete. We used to take caps and hit them with a hammer on the sidewalk. That and popsicle-stick architecture ... ah BLISS!!!
