Taking another trip down memory lane here. Different things of a mechanical nature held a certain fascination with me - old style elevators with operators, streetcars, trains, steel wrecking balls knocking down buildings. But, what held the greatest fascination for me as a pre-school age child was garbage trucks! When I would hear the truck coming down the alley I would run to the end of our backyard, still in my jammies, to watch the men banging metal trash cans into the back of the truck and banging the empties back on the concrete again. Once the truck back area was reasonably full, one guy would pull down a door and pull on a handle that would activate the trash compacting sequence. Once done, the door would pop open on it's own and the trash was gone, into the bowels of the truck body.
When I turned 5, we moved to an apartment building, but my fascination with trash disposal trucks continued. Now, old enough to venture around the immediate neighborhood, I knew what days trash was collected and would follow the truck for blocks. My mother actually looked all over for a toy trash truck for me to play with - and found one! It was all metal with rubber tires (as most wheeled toys were in the 1950's) and had a dumper you could fill with *trash*. There was a handle to crank the dumper up and, as it went up, a door opened up for the dumper to unload the trash into the truck. The truck could be tipped back when full, and a bottom door would automatically open to unload all the truck's contents. Pretty neat, one-of-a-kind toy! Wish I still had it. Anyway, that was my biggest fascination as a child.....how about you?
