Bungee Kid...the next pic is also relevant to the where of this all.  A fairly nearby small city was formed very quickly in the early 1940's, the intent to develop usable nuclear fuel for the atomic bomb.  This was a Secret City.   There is a festival each year there "sort of" based on the origination of the city but it is for fun and some historical stuff.  

This kid was in harness to bungee cords above a trampoline. He was having a fine time, indeed.
