When I was 4, we moved from Hawaii to CT (we landed in NY), and I remember staring out the window of the plane and seeing the George Washington bridge for the first time, and I asked my dad, "what's the Golden Gate bridge doing over here?"
As for puppy chow, I just started making that this past summer, and I still make it all the time! It's good stuff!
And yes, snap bracelets... they got banned from my elem. school. But my friend somehow located a fuzzy one last year... I was playing with it and it cut my wrist. Those things are fun, but they really are dangerous!
Anyone remember tamogachis? And gigipets... and whatever else was out.
