It is a creepy sign. It's obviously been done professionally too; I recognise the font from my graphic design education days. ('Antique Olive', if anyone was curious, even though it doesn't look antique at all.)
The eighteen-wheeler-on-the-Coquihalla story reminded me of my own 'almost met God face-to-face' experience. We had just passed The Sign, actually, and were heading east. I don't know how it happened, because I was asleep, but I assume my friend the driver thought he'd take a little nap too, because when I woke up we were flying through the air. I think we must've flipped end-over-end a few times. We broke a pile of bones -- nine or ten vertebrae between us -- and the amazing thing is that we're still walking and hiking and whatnot. It threw that sign into perspective; I wonder if that was the motivation behind the sign.
Anyway, I guess God did kinda show up; otherwise I don't know how we survived that crash, let alone be able to walk afterwards.
