This is one that I know a lot of Pentax Forums members are interested in, because I see lots of single pictures on this theme. There are some great threads for ghost towns, abandoned buildings and such, but what about one for the mechanical devices that finally got pushed into an out of the way spot and left to rust away into oblivion? Let's see some of these old ghosts.
Here is a Yellow Truck and Coach road tractor. Yellow was GM's truck and bus division starting in 1925. It was restructured into GMC in 1943. There is lots of information available about the buses, but the trucks and road tractors seem to be forgotten - even though most years there were 10 to 20 times as many built as of buses. I found this old thing along a creek at the edge of town.
It took copious applications of spit applied by hand to get the builder's plate clean enough to read.
