ZFR: I'd say don't waste time hunting for it. Just sleep on it and maybe illumination will strike you suddenly one moment.
If not, wait till next weekend.
I assume the later. I hope I don't offend anyone or look bold, just make an assumption - so, I am currently stuck in the same place where I initially did. I assume I was among the first members, if not the first, who went through first two "gates" and then starved on input.
As analogy, I traveled in the bus then in the car and it then got stuck. I understood it lacks gasoline, I just can't find any opening. This is about the time when I contacted you in PM.
So then I got the LoTR reference and started thinking over it, still finding nothing on the car, whilst tasting it detail per detail (I couldn't take it apart, due to not being engineer in cars). Yes I "smoked" through the manuals about the reference.
In the end, I walked back into my starting point and discovered strange hollow spaces in car garage. But the car is still out there, waiting for gasoline. Perhaps the gasoline is in the hollow space? Perhaps its somewhere inside the car? I tried my best to no avail.
So here lies the skeleton of [url=http://fallout.wikia.com/wiki/Ed_(Fallout)]Lin545[/url].
It looks: dead.
