Interesting thread idea.
Hmmmm……
-Learning that the United States was the most powerful country in the world.
-Finding out an acquaintance’s father drove a taxi (infinitely cooler than a boring office job).
-Learning Moshiach is coming by the year 6000 (practically around the corner!)
-Seeing postage stamps from Israel! With Hebrew lettering!
-Xerox machines (much better than mimeographs). And they don’t even destroy the original!
-Electric pencil sharpeners. (who hasn’t sharpened a pencil down to a nub when first trying out an electric sharpener?)
-A shul that had a Candy Lady as well as a Candy Man (really!)
-Koirim on RH and YC. Al Chait on YC.
-The Entebbe raid and rescue.
-Watching the milkman deliver in the predawn hours. They really didn’t have a driver’s seat in those trucks.
-Seeing trains on McDonald Avenue. Not on the elevated line, but on the street itself.
-President Ford coming to Yeshiva of Flatbush to speak.
-Rabeim actually playing baseball with us on Lag B’Omer.
-Heavier-than-air flight. (just checking if you read this far.)
