But I'm afraid I've forgotten quite a bit.
The day I left the assembly plant and joined engineering was the day the staff split into the "new C/K" GMT400 group and the "carryover C/K" group.*
There was lots of whispers and intrigue and speculation and choosing sides. My only thought was "
please don't send me back to the assembly plant!"
