This is the Lake Allatoona side of Allatoona Dam.  I took this when our son Adam gave me a lake tour as a gift.

If you were on top of the dam and looking down the other side you would see a huge cement cliff and many feet below is the Etowah River.  Over to the right of the river you would see a brick structure which is the remaining ruins of Cooper Furnace which was in full operation before the Civil War. 

AND!!! If you look  up in the sky you might see a few folded paper airplanes floating lazily down until they get too close to the edge of the damn and the west wind coming up the Etowah River hits the dam and go the only way it can, which is up, and scoops up the paper air planes and carries them high above the dam until it lets go and the planes start their floating back down again, maybe for all eternity.

My late friend Sam Carley and I launched the paper airplanes back in about 1961 and they were in their eternal routine before we left.  Sam was a Georgia Tech student and we were working out of his experiments.  *


*If you read this blog regularly,  you already know this, I have told of this scientific experiment  several times.

Another scientific experiment we made:  The theory of relativity  in its simplest form is that if you are  on a bus and jump up in the air you will land on the same spot you left the floor at.  It seems the bus should have moved out from under you so to speak.  But the reason it doesn't is that you are traveling the same speed forward the bus is, even when you jump straight up.  Sam just bought a used Chevvy green and white convertible.  He suggested we ride normal speed, throw a beer can up in the air and stop suddenly.  We did and WHOMP!  The full beer can put a dent on his hood.
