Learn to spell, morons!
It's spelled "Zzyzx" Road, NOT Zyzzyx!
Anyone who has ever driven on Highway 15 between LA and Vegas knows that.
And, when I say "morons" I mean the idiots who made this movie, spelled the title and the name of the road incorrectly (for whatever reason), then thought that the millions of people who drive on Highway 15 every year either wouldn't notice the difference or wouldn't care. Do they think we're stupid?
"Enough of that technical talk, Foo!"
